I have a line in my code that seems to really allocate a lot of memory, and
I think it might be slowing down my program. I have two matrices. The first
matrix A is n-by-2 and the second matrix B is n-by-b. What I need to do is
to multiply the first column of A element by element to each row in B[:,
2:end]. I use broadcasting (.*) to achieve this along with a transpose of
A[:,1]:
C=A[:,1]'.*B[:,2:end]
However, it seems to allocate a lot of temporary memory (the number memory
number in .mem overflows even for small problems). Is there anything I can
do here?
