ge_widthm_i(3PI) Sun Interval Performance Library ge_widthm_i(3PI)NAMEge_widthm_i - Elementwise width of an interval matrix.
DESCRIPTION
C = SUP(A) - INF(A)
The routine GE_WIDTHM_I finds the real matrix C such that
Cij = SUP(Aij)-INF(Aij) for all general interval matrix A entries. The
routine returns immediately if N is equal to zero.
SYNOPSIS
SUBROUTINE GE_WIDTHM_I( A, C )
INTERVAL, INTENT(IN) :: A(:,:)
REAL, INTENT(OUT) :: C(:,:)
where
A and C have shape (M,N).
ARGUMENTS
A (input)
Array of DIMENSION (M,N).
Unchanged on exit.
C (output)
Array of DIMENSION (M,N).
On exit, contains WIDTH(Aij) for all A entries.
ERRORS
blas_error_alloc
A or C is unallocated array
blas_error_shape
shape(A) /= shape(C)
