我们上课用的MATLAB课件，课件不错，就是老师讲的比较差劲。(the ppt of matlab used in my class)

4-pam and simulation the bit error performance

vc与matlab混合编程的具体实例。vc调用matlab的.m函数，经过编译之后转换为C++程序，实现进行混合编程。(vc mixed with Matlab programming specific examples. Vc call Matlab. M function, compiled after the conversion of C procedures, mixed programming.)

bpsk编码很适合出学者,已经经过调试 加了个 升余弦滤波(BPSK encoding is very suitable for the academics, have been debug plus a raised cosine filter)

Set points above level to white, others to black

电动汽车建模，采用m语言编写的电动汽车模型(Electric vehicle modeling language using m electric car model)

iris segmentation matlab code

matlab实现（7，3）循环码编码很简单(matlab realize (7,3) cyclic code is very simple coding)

fit_maxwell_pdf - Non Linear Least Squares fit of the maxwellian distribution. given the samples of the histogram of the samples, finds the distribution parameter that fits the histogram samples. fits data to the probability of the form: p(r) = sqrt(2/pi)*(a^(-3/2))*(r^2)*exp(-(r^2)/(2*a)) with parameter: a format: result = fit_maxwell_pdf( x,y,W,hAx ) input: y - vector, samples of the histogram to be fitted x - vector, position of the samples of the histogram (i.e. y = f(x,a)) W - matrix or scalar, a square weighting matrix of the size NxN where N = length(y), or 0 to indicate no weighting is needed. hAx - handle of an axis, on which the fitted distribution is plotted if h is given empty, a figure is created. output: result - structure with the fields a - fitted parameter VAR - variance of the estimation type- weighted LS or not weighted LS iter- number of iteration for the solution
