C
C PURPOSE
C
C To print an M-by-N real matrix A row by row. The elements of A
C are output to 7 significant figures.
C
C ARGUMENTS
C
C Input/Output Parameters
C
C M (input) INTEGER
C The number of rows of matrix A to be printed. M >= 1.
C
C N (input) INTEGER
C The number of columns of matrix A to be printed. N >= 1.
C
C L (input) INTEGER
C The number of elements of matrix A to be printed per line.
C 1 <= L <= 3.
C
C NOUT (input) INTEGER
C The output channel to which the results are sent.
C NOUT >= 0.
C
C A (input) COMPLEX*16 array, dimension (LDA,N)
C The leading M-by-N part of this array must contain the
C matrix to be printed.
C
C LDA INTEGER
C The leading dimension of array A. LDA >= M.
C
C TEXT (input) CHARACTER*72.
C Title caption of the matrix to be printed (up to a
C maximum of 72 characters). For example, TEXT = 'Matrix A'.
C
C Error Indicator
C
C INFO INTEGER
C = 0: successful exit;
C < 0: if INFO = -i, the i-th argument had an illegal
C value.
C
C METHOD
C
C The routine first prints the contents of TEXT as a title, followed
C by the elements of the matrix A such that
C
C (i) if N <= L, the leading M-by-N part is printed;
C (ii) if N = k*L + p (where k,p > 0), then k M-by-L blocks of
C consecutive columns of A are printed one after another
C followed by one M-by-p block containing the last p columns
C of A.
C
C Row numbers are printed on the left of each row and a column
C number appears on top of each complex column.
C The routine uses 2 + (k + 1)*(m + 1) lines and 7 + 32*c positions
C per line where c is the actual number of columns, (i.e. c = L
C or c = p).
