C        SUBROUTINE GMTRA
C
C        PURPOSE
C           TRANSPOSE A GENERAL MATRIX
C
C        USAGE
C           CALL GMTRA(A,R,N,M)
C
C        DESCRIPTION OF PARAMETERS
C           A - NAME OF MATRIX TO BE TRANSPOSED
C           R - NAME OF RESULTANT MATRIX
C           N - NUMBER OF ROWS OF A AND COLUMNS OF R
C           M - NUMBER OF COLUMNS OF A AND ROWS OF R
C
C        REMARKS
C           MATRIX R CANNOT BE IN THE SAME LOCATION AS MATRIX A
C           MATRICES A AND R MUST BE STORED AS GENERAL MATRICES
