[Numpy-discussion] How to Extract the Number of Rows and Columns in a Matrix

2012-03-26 Thread Stephanie Cooke
Hello, I would like to extract the number of rows and columns of a matrix individually. The shape command outputs the rows and columns together, but are there commands that will separately give the rows and separately give the columns? Thanks ___

len(M) will give you the number of rows of M. For columns I just use M.shape[1] myself, I don't know if there exists a shortcut. -=- Olivier Le 26 mars 2012 19:03, Stephanie Cooke cooke.stepha...@gmail.com a écrit : Hello, I would like to extract the number of rows and columns of a matrix
