a basic operations on images using matlab

floyd求解最短路，并将路径还原。经过验证，程序中有清楚注释(floyd Solving the shortest path, and path restoration. After authentication, the Notes program has clearly)

8 band kp method calculate the valence band structure, using finite difference method

运行optical.m文件，进入gui界面，能够实现对lens镜片，高度，宽度，半径等的调整，能够追迹光线，并调整光线的颜色，并输出追迹后的数据，焦点等数据(Run optical. M file, into the GUI interface, can realize the lens glasses, height, width, radius and adjustment, can tracing the light, and adjust the color of the light, and output the data after tracing, focus and other data)

ok, i have done, this programa calculating transient eletrical system at indonesian

这是一个（2.1.3）卷积码编码、BSC信道传输、Viterbi译码组成的程序合集，运行main.m即可得到仿真结果(This is a (2.1.3) convolutional code, Viterbi decoding, BSC channel transmission is composed of collection procedures, running main.m can be obtained by the simulation results)

粒子群优化算法pso的matlab程序,测试函数为Sphere函数,可以直接使用,其他函数可以自己更改(PSO pso matlab program, test the function of Sphere function, can be used directly, other functions can own change)

OFDM的调制过程，已经运行过，比较不错，过程很清晰(OFDM modulation process has been run before, quite good, the process is very clear)

该代码仅计算了一个101×101尺寸的Gabor函数变换，得到均值和方差。代码采用两种卷积计算方式，从结果中可以看出，快速傅立叶变换卷积的效率是离散二维叠加和卷积的近50倍。 (The code is only the calculation of a 101 × 101 size Gabor function transformation, the mean and variance. Convolutional code using two methods of calculation can be seen from the results, fast Fourier transform convolution efficiency are two-dimensional discrete convolution superposition and nearly 50 times.)

it describes the detection technique of canny edge detection algorithm.
