先学了R,最近刚刚上手python,所以想着将python和R结合起来互相对比来更好理解python。最好就是一句python,对应写一句R。 python中的numpy模块相当于R中的matirx矩阵格式,化为矩阵,很多内容就有矩阵的属性,可以方便计算。 以下符号: =R= 代表着在R中代码是怎么样的。

Rather, the distance (in elements) between the start of two successive columns is the same as the parent matrix, and is called the leading dimension of the matrix (here stored as ld). A similar remark holds for row major matrices, where ld is the number of elements between the beginning...
