Hi everyone,

I have a question to solve linear equations with argument is a matrix.
For example, X is a q by p matrix satisfies

F(X)=A and t(B)%*%X+t(X)%*%B=0,

where A and B are known q by p matrices and 0 is p by p matrix with
all elements are 0s. And F(.) is a known function of matrix, X.
Now, I try to solve X. Can anyone help me? Thanks a lot.
