MATLAB in medical data processing of video physics experiment applies mediumly

[summary] analytic MATLAB in school of college of medicine education of video physics experiment applies mediumly, pointed out the meaning that MATLAB popularizes in education of medical foundation experiment and feasibility, be in according to the author the experience that medicine uses MATLAB in activity of education of video physics experiment, offerred the MATLAB processing technique of experimental data.

Foreword

Teach the development that learns reform pace to get used to the whole nation, promote discipline of school of college of medicine construction and curricular system construction in the round, each medicine school encourages fundamental class and professional class teacher actively to launch the attempt that experimental subject education reforms. Be in through us " medicine is video physics " , " electrician learns " the practice that applied MATLAB develops to undertake an analysis to experimental data in waiting for education of fundamental tax test, abounded the connotation of experimental subject education, the interest that aroused a student to apply modern method to handle an issue and the ability that solve a problem. This research is in " medicine is video physics " the experience in MATLAB applying in experimental subject education undertook summing up, use teacher and student single case undertook an analysis.

MATLAB reachs development existing state of affairs in the application on international education and scientific research

MATLAB already became a function to compare the software with powerful, steady performance, received extensive attention and application. In Euramerican university, the schoolbook of the course such as analysis of alignment of statistic of algebra of such as application, several manage, automata, number and signal processing, imitate and digital communication, time, dynamic system simulation regards content as MATLAB, the discriminative sex that became 90 time schoolbook and old edition book almost indicates. Over MATLAB is the main tool that unripe, doctoral student must master the undergraduate that assiduously studies degree, Master. In international academia, MATLAB has been considered as software of accurate, reliable scientific computation standard truly. Go up in the academic journal with a lot of top-ranking international (especially information science journal) , can see the application of MATLAB. MATLAB collect computation, visible reach process designing at a suit. No matter be of the problem,put forward in MATLAB, the expression that still is a result uses habitual maths to describe a method, and the aftertreatment before the programming language that does not need a convention undertakes. This one characteristic makes MATLAB made the favorable environment that mathematical analysis, algorithmic development and applied process develop. It is calculated analysis, scientificly in data, emulate, the effect with the bigger and bigger move since the domain such as analysis of processing of automata, signal and communication, graph and processing, image processing.

The current situation that MATLAB uses in our country college and the necessity in education of medical test subject

The exercise after reasonable engineering course carries out education, undergraduate students class, and strength is being increased to introduce MATLAB in activity of scientific research of average college teacher. However MATLAB is carried out in education of undergraduate course of school of college of medicine medium specific apply be in start level. MATLAB serves as a kind brand-new, direct education form, with its graphical means states the abstract equation that figure reason to have special expressional force, can raise a student the understanding to the problem and the interest to academic tax education. MATLAB is used to seek solution in exercise of the exercises after the class, can raise a student to independence is analysed and solve the ability of the problem, self-study of the student after increasing a tax and consolidate the strength that increase and deepness. Make abstract maths, video physics, image handles the advanced method that waits for a large number of course and contemporary computer and methodological couple, make foundation, orthodox course enters modern science and world education tide. And MATLAB introduces in experimental subject, it is the key that curriculum of school of college of medicine reforms. Before the student of major average college is in finish after the experiment, undertaking to much data chart changes analysis, comparative analysis and error analysis is the in draw of squared paper begin means that uses convention, both neither is beautiful not accurate also. Use the MATLAB science with accepted international to analyse a method to be able to be changed to data chart, the error analyses standardization. Introduce MATLAB in scientific research, will raise the scientific sex of scientific research, replace the method of scientific analysis. When science of the great majority on this age bound the magazine is collecting the analytic means that the author recommends to use MATLAB when the paper is published, master law of this one party to process the data that collects in scientific research so, undertake the analysis is the tool that the researcher in current and scientific research must master. The chart of MATLAB analysed a method to enhance the level of scientific research and arrangement. Introduce MATLAB in teacher and student of common medicine school, scientific research so, press action to raising the level of education scientific research of the school to will remove huge.

MATLAB is in " medicine is video physics " the application on experimental education

Be in " medicine is video physics " in the experiment, data processing is the main component of physical experiment and crucial link, also be a when evaluate physical test result main index. Because experimental data bulk is great, computational formula is more, the manual processing of data is very trival. If be in calculative process, use MATLAB to undertake process designing is handled, OK the consideration with much leave out. MATLAB is in " medicine is video physics " the application in experimental subject education has very clear advantage, be operated namely and use a method very simple, the person that should have learned a kind of computer language only can master its process designing method very quickly. Rich in-house function can solve a lot of complex operation and data processing and analysis, powerful graphical function can use graphical method to convey computational result, intuitionistic and accurate. We will be used below " medicine is video physics " experimental photoemission and Pulangke determine invariably try to analyse. In the experiment we are measured rightly the voltage parameter of the correspondence of place of 5 kinds of color of one class stripe sees a table 1.

Express 1
The voltage parameter of correspondence of place of 5 kinds of color (slightly)

Graph 1
The curve of the biggest kinetic energy that uses MATLAB scale and frequency (slightly)

After the experiment ends, the program that the student designs according to us inputs the experimental data that they measure, the standard curve that travel operation can reach experimental result and place need directly is entered on common computer with MATLAB.

Last word

Process experimental data with MATLAB, the process is intuitionistic and convenient, simple command can finish trival computation, also aroused study interest of the student at the same time, let a student cast off dry repetition to calculate. Because MATLAB has the digital figure of outstanding digital computation ability, accurate science visible ability and intuitionistic and concise program environment, because this can be in school of college of medicine on the experimental education of each course extensive promotion.
