The @TRANSPOSE function returns the transpose of matrix A. The syntax for @TRANSPOSE is:

T = @TRANSPOSE( A);

Matrix A does not have to be square, but if A is an mxn matrix, then T must be of dimension nxm.  In addition, both matrices must be dense and cannot be defined on sparse sets, and @TRANSPOSE may only be used in a model's calc section.
