Application of MATLAB in Physical Experiment Processing

Take the data processing of the volt-ampere characteristic of diode experiments and the single slit Fresnel diffraction for example, this paper gives an introduction to Matlab in physical experiment processing. Compared with traditional experiment methods, the application of Matlab in experiment data processing can avoid the error effectively which caused by manual handling, and the Matlab method is simple to operate. While the simulation to single slit Fresnel diffraction gives a more precise study on the diffraction phenomenon of light.
