10
11           CHARACTER      UPLO
12
13           INTEGER        LDA, LDB, M, N

ARGUMENTS

23       UPLO    (input) CHARACTER*1
24               Specifies the part of the matrix A to be copied to B.   =  'U':
25               Upper triangular part
26               = 'L':      Lower triangular part
27               Otherwise:  All of the matrix A
28
29       M       (input) INTEGER
30               The number of rows of the matrix A.  M >= 0.
31
32       N       (input) INTEGER
33               The number of columns of the matrix A.  N >= 0.
34
35       A       (input) DOUBLE PRECISION array, dimension (LDA,N)
36               The m by n matrix A.  If UPLO = 'U', only the upper triangle or
37               trapezoid is accessed; if UPLO = 'L', only the  lower  triangle
38               or trapezoid is accessed.
39
40       LDA     (input) INTEGER
41               The leading dimension of the array A.  LDA >= max(1,M).
42
43       B       (output) DOUBLE PRECISION array, dimension (LDB,N)
44               On exit, B = A in the locations specified by UPLO.
45
46       LDB     (input) INTEGER
47               The leading dimension of the array B.  LDB >= max(1,M).
