Thanks for your response!
While each row should contain a defined number of fields/elements,
the actual amount of rows is dependent on the length of the array.
So I'm thinking rows would need to be defined by dividing the
${#ARRAY[@]} by desired number of columns then adding 1
( for the remainder ).
Does this sound logical?
Thanks again! ...This is elementary to many of you, but I'm having
a bit of trouble working this out.

SORGLQ(l) ) SORGLQ(l)
NAME
SORGLQ - generate an M-by-N real matrix Q with orthonormal rows,
SYNOPSIS
SUBROUTINE SORGLQ( M, N, K, A, LDA, TAU, WORK, LWORK, INFO )
INTEGER INFO, K, LDA, LWORK, M, N
REAL A( LDA, * ), TAU( * ), WORK( * )
PURPOSE
SORGLQ generates an M-by-N real matrix Q with orthonormal rows, which is defined as the first M rows of a product of K elementary reflec-
tors of order N
Q = H(k) . . . H(2) H(1)
as returned by SGELQF.
ARGUMENTS
M (input) INTEGER
The number of rows of the matrix Q. M >= 0.
N (input) INTEGER
The number of columns of the matrix Q. N >= M.
K (input) INTEGER
The number of elementary reflectors whose product defines the matrix Q. M >= K >= 0.
A (input/output) REAL array, dimension (LDA,N)
On entry, the i-th row must contain the vector which defines the elementary reflector H(i), for i = 1,2,...,k, as returned by
SGELQF in the first k rows of its array argument A. On exit, the M-by-N matrix Q.
LDA (input) INTEGER
The first dimension of the array A. LDA >= max(1,M).
TAU (input) REAL array, dimension (K)
TAU(i) must contain the scalar factor of the elementary reflector H(i), as returned by SGELQF.
WORK (workspace/output) REAL array, dimension (LWORK)
On exit, if INFO = 0, WORK(1) returns the optimal LWORK.
LWORK (input) INTEGER
The dimension of the array WORK. LWORK >= max(1,M). For optimum performance LWORK >= M*NB, where NB is the optimal blocksize.
If LWORK = -1, then a workspace query is assumed; the routine only calculates the optimal size of the WORK array, returns this
value as the first entry of the WORK array, and no error message related to LWORK is issued by XERBLA.
INFO (output) INTEGER
= 0: successful exit
< 0: if INFO = -i, the i-th argument has an illegal value
