ideas for perl script - strings,conditionals..etc
I have a matrix , how do I compare all the elements of a column , lets say I want to check if the columns contain the alphabets "S","H","A","R","A","T".
and not "X"s.

Lets say matrix looks something like this ..

SSSXSH
HHXXHA
AAXXAT
RRRXRS
AAXTAR
TTTTTA




I can hard code it where $AA[0][$j] , $AA[1][$j] , $AA[2][$j] .. is the row and column ... like this ..


for($j=0;$j<$len;$j++){
if($AA[0][$j] eq "what goes here??" && $AA[1][$j] eq "A" && $AA[2][$j] eq "A"){
print "blah blah \n";
exit;}
else{}
}



what I would like to do is put it in 2 for loops like this...

for($i=0;$i<3;$i++){
for($j=0;$j<$len;$j++){
if($AA[$i][$j] eq one of the characters S,H,A,R,A,T..what I do here??? ){
print "blah blah \n";
exit;}
else{}
}
}

Tips ideas and code are welcome.

zgeqrt2.f

zgeqrt2.f(3)							      LAPACK							      zgeqrt2.f(3)

NAME

       zgeqrt2.f -

SYNOPSIS

   Functions/Subroutines
       subroutine zgeqrt2 (M, N, A, LDA, T, LDT, INFO)
	   ZGEQRT2

Function/Subroutine Documentation
   subroutine zgeqrt2 (integerM, integerN, complex*16, dimension( lda, * )A, integerLDA, complex*16, dimension( ldt, * )T, integerLDT,
       integerINFO)
       ZGEQRT2

       Purpose:

	    ZGEQRT2 computes a QR factorization of a complex M-by-N matrix A,
	    using the compact WY representation of Q.

       Parameters:
	   M

		     M is INTEGER
		     The number of rows of the matrix A.  M >= N.

	   N

		     N is INTEGER
		     The number of columns of the matrix A.  N >= 0.

	   A

		     A is COMPLEX*16 array, dimension (LDA,N)
		     On entry, the complex M-by-N matrix A.  On exit, the elements on and
		     above the diagonal contain the N-by-N upper triangular matrix R; the
		     elements below the diagonal are the columns of V.	See below for
		     further details.

	   LDA

		     LDA is INTEGER
		     The leading dimension of the array A.  LDA >= max(1,M).

	   T

		     T is COMPLEX*16 array, dimension (LDT,N)
		     The N-by-N upper triangular factor of the block reflector.
		     The elements on and above the diagonal contain the block
		     reflector T; the elements below the diagonal are not used.
		     See below for further details.

	   LDT

		     LDT is INTEGER
		     The leading dimension of the array T.  LDT >= max(1,N).

	   INFO

		     INFO is INTEGER
		     = 0: successful exit
		     < 0: if INFO = -i, the i-th argument had an illegal value

       Further Details:

	     The matrix V stores the elementary reflectors H(i) in the i-th column
	     below the diagonal. For example, if M=5 and N=3, the matrix V is

			  V = (  1	 )
			      ( v1  1	 )
			      ( v1 v2  1 )
			      ( v1 v2 v3 )
			      ( v1 v2 v3 )

	     where the vi's represent the vectors which define H(i), which are returned
	     in the matrix A.  The 1's along the diagonal of V are not stored in A.  The
	     block reflector H is then given by

			  H = I - V * T * V**H

	     where V**H is the conjugate transpose of V.
