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. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
