<B>Mode Parameters</B>
<PRE>
JOB CHARACTER*1
Specifies the part of the matrix A to be transposed into B
as follows:
= 'U': Upper triangular part;
= 'L': Lower triangular part;
Otherwise: All of the matrix A.
</PRE>
<B>Input/Output Parameters</B>
<PRE>
M (input) INTEGER
The number of rows of the matrix A. M >= 0.
N (input) INTEGER
The number of columns of the matrix A. N >= 0.
A (input) DOUBLE PRECISION array, dimension (LDA,N)
The m-by-n matrix A. If JOB = 'U', only the upper
triangle or trapezoid is accessed; if JOB = 'L', only the
lower triangle or trapezoid is accessed.
LDA INTEGER
The leading dimension of the array A. LDA >= max(1,M).
B (output) DOUBLE PRECISION array, dimension (LDB,M)
B = A' in the locations specified by JOB.
LDB INTEGER
The leading dimension of the array B. LDB >= max(1,N).
