产生两个均值为m,方差为sgma的高斯随机变量，当输入参数只有一个时，认为均值为0。(mean to have two m, sgma variance for the Gaussian random variables, when only one input parameters, that the mean of 0.)

图像分形盒维数的算法源程序.此算法是基于黑白二值图像的，因此，需要对导入的图片进行二值化处理，因此算法存在一定误差，但是此算法误差控制在4 以内(Image fractal dimension algorithm source code box This algorithm is based on black and white binary image, and therefore, need to import the picture binarization processing, so the algorithm there are some errors, but this algorithm is less than 4 error control)

this is the linearized model of the power system

matlab的60个小程序，自己找的，感觉不错，可以当模板来用，供大家学习与交流。(matlab 60 small programs, they seek for themselves, feel good, when the template to use for them to learn and exchange.)
