I have a simple program I am running where I define a matrix C, then define
B=C.right_kernel()
I would then like to create another matrix, D, that is a block matrix with C and B as blocks, C on top of B. So far my code for that is
Dlist = []
for i in range(len(rowsofmatrix)):
Dlist.append(C[i,:])
for i in range(20-len(rowsofmatrix)):
Dlist.append(B[i,:])
where rowsofmatrix is a list I used to define the matrix C. The Dlist.append(C[I,:]) works just fine, but the second one involving B does not, and I imagine this has something to do with the form of B. Is there a way I can express B as a regular matrix? Or, alternatively, is there a better way to do this altogether?
