Bug PERL: How do i print an associative matrix?

Hello guys,

I have in PERL an associative 2-dimensional array, called matrix. The array (actually the matrix) is made up like this
Code:
matrix[a][c] = x;
matrix[a][d] = y;
matrix[b][c] = w;
matrix[b][d] = z;
...

but the names a, b, c, d are set just at runtime.

The question is: how can i get all the keys of the matrix (i.e. a, b, c, d) and print the all matrix?

Thank you very much for your help!

Sergio

NAME
zlacp2.f - SYNOPSIS
Functions/Subroutines subroutine zlacp2 (UPLO, M, N, A, LDA, B, LDB) ZLACP2 copies all or part of a real two-dimensional array to a complex array. Function/Subroutine Documentation subroutine zlacp2 (characterUPLO, integerM, integerN, double precision, dimension( lda, * )A, integerLDA, complex*16, dimension( ldb, * )B, integerLDB) ZLACP2 copies all or part of a real two-dimensional array to a complex array. Purpose: ZLACP2 copies all or part of a real two-dimensional matrix A to a complex matrix B. Parameters: UPLO UPLO is CHARACTER*1 Specifies the part of the matrix A to be copied to B. = 'U': Upper triangular part = 'L': Lower triangular part Otherwise: All of the matrix A M M is INTEGER The number of rows of the matrix A. M >= 0. N N is INTEGER The number of columns of the matrix A. N >= 0. A A is DOUBLE PRECISION array, dimension (LDA,N) The m by n matrix A. If UPLO = 'U', only the upper trapezium is accessed; if UPLO = 'L', only the lower trapezium is accessed. LDA LDA is INTEGER The leading dimension of the array A. LDA >= max(1,M). B B is COMPLEX*16 array, dimension (LDB,N) On exit, B = A in the locations specified by UPLO. LDB LDB is INTEGER The leading dimension of the array B. LDB >= max(1,M).
