F06WNF (ZLANHF) returns the value of the
1-norm, the
∞-norm, the Frobenius norm, or the maximum absolute value of the elements of a complex Hermitian matrix
A stored in Rectangular Full Packed (RFP) format.
The RFP storage format is described in
Section 3.3.3 in the F07 Chapter Introduction.
Given a complex
n by
n symmetric matrix,
A,
F06WNF (ZLANHF) calculates one of the values given by
A1=maxj∑i=1naij |
(the 1-norm of A), |
A∞=maxi∑j= 1naij |
(the ∞-norm of A), |
AF=∑i=1n∑j=1naij21/2 |
(the Frobenius norm of A), or |
maxi,jaij |
(the maximum absolute element value of A). |
None.
None.
Not applicable.
None.
This example reads in the lower triangular part of a symmetric matrix, converts this to RFP format, then calculates the norm of the matrix for each of the available norm types.
