# Math Help - Need help for matrix operation

1. ## Need help for matrix operation

I am having matrix equation

A= B x C

Where B= 0 1 0
1 0 0
1 1 0
1 1 0

and C = 1 1 0 1 0 0
0 1 1 0 1 0
1 0 1 0 0 1

And by equation A= B x C my answer is

A= 0 1 1 0 1 0
1 1 0 1 0 0
1 0 1 1 1 0
1 0 1 1 1 0

****************************
I want to ask If A and B are known to me , how can i calculate C

I tired C= A x B(inverse)

in matlab but it gave error
Kindly help me to calculate C if A and B are known

Hi there.

You can multiply both sides of the equation by $B^{-1}$, but from the left side.

i.e. $C=B^{-1}A$

not $C=AB^{-1}$
