Description (last modified by rbeezer) (diff)
This was requested in the 2011 Sage MAA PREP workshop. Names deleted.
: Is there any way to delete specified rows or columns from an existing matrix? : Hmm, I think that is possible, using a method. : I'll look. : - we can swap rows, scale rows, add mults of rows, create a matrix from specified rows... but not that. : Would you find this useful? Is it in Matlab? : For list there is a method called pop : Right, but not for matrices. : if matrix is a list of list... : But it's not quite that. : I'l make a ticket. : this would be useful : there is an m.insert_row : Hah! But we can't do it backwards
So let's make this happen.
