About the Fast Fourier Transform, i think it is (w64)^2 = w32, however, the pdf make it (w32)^2 = w64

前几讲的笔记做得非常好,渴望见到后面课程的笔记,谢谢!

此处文字描述中，两个矩阵的顺序颠倒了：

Dear author, hello ! I am a graduate student majoring in statistics. I am fascinated by your article on the use of PyGSLIB for resource estimation of this geological algorithm. I have run through your code and understand the meaning of most of the data in the data file. However, the meaning of the CU data column in the assay _ BABBITT data file is not clear. Can you tell me the meaning of this data column ?

“一个经典的例子就是：在消元过程中，当矩阵主元 位置上面不是 1 时，我们就需要用行变换将主元位置换回 1。”
应该说主元位置上是0时，我们需要通过行变换来将主元换成0
