PURPOSE

21       DLASCL multiplies the  M  by  N  real  matrix  A  by  the  real  scalar
22       CTO/CFROM.   This  is  done without over/underflow as long as the final
23       result CTO*A(I,J)/CFROM does not over/underflow. TYPE specifies that  A
24       may  be  full, upper triangular, lower triangular, upper Hessenberg, or
25       banded.

ARGUMENTS

28       TYPE    (input) CHARACTER*1
29               TYPE indices the storage type of the input matrix.  =  'G':   A
30               is a full matrix.
31               = 'L':  A is a lower triangular matrix.
32               = 'U':  A is an upper triangular matrix.
33               = 'H':  A is an upper Hessenberg matrix.
34               =  'B':   A  is a symmetric band matrix with lower bandwidth KL
35               and upper bandwidth KU and with the only the lower half stored.
36               =  'Q':   A  is a symmetric band matrix with lower bandwidth KL
37               and upper bandwidth KU and with the only the upper half stored.
38               =  'Z':   A  is a band matrix with lower bandwidth KL and upper
39               bandwidth KU.
40
41       KL      (input) INTEGER
42               The lower bandwidth of A.  Referenced only if TYPE =  'B',  'Q'
43               or 'Z'.
44
45       KU      (input) INTEGER
46               The  upper  bandwidth of A.  Referenced only if TYPE = 'B', 'Q'
47               or 'Z'.
48
49       CFROM   (input) DOUBLE PRECISION
50               CTO     (input) DOUBLE PRECISION The matrix A is multiplied  by
51               CTO/CFROM.  A(I,J)  is  computed  without over/underflow if the
52               final  result  CTO*A(I,J)/CFROM  can  be  represented   without
53               over/underflow.  CFROM must be nonzero.
54
55       M       (input) INTEGER
56               The number of rows of the matrix A.  M >= 0.
57
58       N       (input) INTEGER
59               The number of columns of the matrix A.  N >= 0.
60
61       A       (input/output) DOUBLE PRECISION array, dimension (LDA,N)
62               The  matrix  to  be  multiplied by CTO/CFROM.  See TYPE for the
63               storage type.
64
65       LDA     (input) INTEGER
66               The leading dimension of the array A.  LDA >= max(1,M).
67
68       INFO    (output) INTEGER
69               0  - successful exit <0 - if INFO = -i, the i-th  argument  had
70               an illegal value.
