Web19 feb. 2014 · try to store the result of a to_array(matrix) in a real[,] when the result is, in fact, a real[]. Parser wouldn't mind, but compiler would. But, this would happen only if you used fixed size matrices, but I see now that Stan uses only Eigen::Dynamic for matrices. So to_array(matrix) will always return real[,]. WebTo make the statement A*I=A to be true, the identity matrix need to be 2x2 matrix. But to make the statement I*A=A to be true, the identity matrix in this case need to be a 3x3 matrix. You can see these two matrices are not equal. • ( 14 votes) Upvote Downvote CCDM 3 years ago You are correct.
