Matlab_Signal_Processing

An alternative to Matlab s HIST, function HISTW prevents extreme values in top and bottom percentiles of an input vector affecting the histogram s scaling, obscuring location and shape of the distribution s main mass. Limits of x and y (maximum only) axes can be set, and a marker line drawn at given x position. In contrast to HIST, bin size can be explicitly specified, and relative, rather than absolute, frequencies are plotted.

说明：  这是一个计算镜头视场的软件，非常简单但是很实用。(This is a calculation of the lens field of view of the software, very simple but very practical.)
