matlab的三维图形显示代码，没有错误，有很好的参考价值(3D image view based on matlab)

重装系统后恢复matlab文件关联,重装系统后，若没动MATLAB安装目标，则MATLAB不用重新安装。（同样的原因，可以移动MATLAB安装目标）对MATLAB相关文件，建立重新关联就行了。(Reinstall the system restore matlab file association, reinstall the system, if no action MATLAB installation target, MATLAB without having to reinstall. (For the same reason, you can move MATLAB installation target) on MATLAB related files, to establish re-associate on the line.)

Retinex算法matlab实现，用于处理图像光照不均匀。(Matlab implementation of Retinex algorithm)

用双线性变换法设计IIR数字滤波器 滤波就是将外界干扰的不需要的频率滤除掉，一面影响要测试数据的结果。比如如果是心电波的话，如果这是外界有很大的噪声干扰，滤波就是把不必要的信号给抑制掉，以便对心跳的正常测试。通过图比较，滤波后的明显比之前的要平滑，就是滤去干扰噪声的结果。采样间隔对实验有影响，取的过大会导致频率混叠。(Bilinear transformation method using digital filter IIR filter design is to outside interference filter out unwanted frequencies, while the impact to test data results. For example, if it is so heart waves, if this is a great noise outside interference, filtering is unnecessary signal out to the curb in order to test the normal heartbeat. Through chart comparison, after filtering than before to smooth the noise interference is the result of least squares. Sampling interval of the experiment affect take-off frequency of the General Assembly leading to aliasing.)
