Matrix algebra AxB=C, I want to solve for B

3 views (last 30 days)
I have the following matrix equation: A[4x1826] * B[1826x5]=C[4x5]
I have A and C and want to calculate B but I can't remember my matrix algebra because I'm too dumb and old.
Can anyone help me out?

You can't recover the "original" B, whatever it is, your system is underdetermined (much more unknowns - 1826 - than equations - 4). MATLAB "\" gives ONE solution.

That's right, my answer was totally wrong. I delete it to avoid confusion. Thanks Bruno!
