normest
2-norm estimate
Syntax
nrm = normest(A)
[nrm, count] = normest(A)
nrm = normest(A, tolerance)
[nrm, count] = normest(A, tolerance)
Input argument
A - Input matrix
tolerance - Relative error tolerance
Output argument
nrm - Matrix norm: scalar.
count - Number of power iterations: scalar.
Description
nrm = normest(A) returns an estimate of the 2-norm of the matrix A.
Example
M = [ 0 2.4495 0 0 0 0 0
2.4495 0 3.1623 0 0 0 0
0 3.1623 0 3.4641 0 0 0
0 0 3.4641 0 3.4641 0 0
0 0 0 3.4641 0 3.1623 0
0 0 0 0 3.1623 0 2.4495
0 0 0 0 0 2.4495 0];
[nrm, count] = normest(M)
