n

INTEGER. Specifies number of columns in the matrix A.

a

REAL for ilaslr

DOUBLE PRECISION for iladlr

COMPLEX for ilaclr

DOUBLE COMPLEX for idazlr

Array, DIMENSION(lda, *). The second dimension of a must be at least max(1, n).

Before entry the leading n-by-n part of the array a must contain the matrix A.
