Good Afternoon,
I know this is probably a silly question to ask but if I have matrices A, B, C and D. With the equation
D=A*(-B*C)
and I want to solve for C. Is there any possible way to do this?
I have thought of this. D=(A*-B)
C=D/E
Thanks,
Mel

Matrix multiplication is associative so A*(-B*C) is the same as -(A*B)*C . So you can use the \ matrix division operator between D and -(A*B)

Is x a vector? If so then there is usually no unique solution.
Are we given any information restricting any of the arrays to be square ?
