Matrix dimensions must agree error for backslash.

Hi all, I have a 1080x1080 matrix A and 1x1080 matrix B. The values in matrix B are all zeroes except for two values. When I use A\B, I get the 'Matrix dimensions must agree.' error. Where am I going wrong?

Try A\B'

Thanks! I go an output. But why didn't I get this when I just used B instead of B'?

B should be a column matrix with rows equal to rows in A.B' is transpose of B. 1*1080 is transposed to 1080*1.
