MATLAB: Multiply each column by a elements of cell array

Question

hey

i have a matrix like this:

matrix=
0  2  4
3  0  0
0  1  0
3  0  1
0  0  0
and cell array:   mul={1,1,0.6,0.6,0.3}

i want to multiply all columns by 'mul' and then add. e.g. [0x1 + 3×1 + 0x0.6 + 3×0.6 + 0x0.3] and same for all other columns.

Thanks

Answer 1

matrix=[0  2  4
3  0  0
0  1  0
3  0  1
0  0  0];
mul={1,1,0.6,0.6,0.3} ;
iwant = sum(bsxfun(@times,matrix,[mul{:}]'))
