DSP Blockset

Matrix 1-Norm

Compute the 1-norm of a matrix.

Library

Math Functions / Matrices and Linear Algebra / Matrix Operations

Description

The Matrix 1-Norm block computes the 1-norm, or maximum column-sum, of an M-by-N input matrix, A.

This is equivalent to

• y = max(sum(abs(A)))     % Equivalent MATLAB code
  
  
  

A length-M 1-D vector input is treated as an M-by-1 matrix. The output, y, is always a scalar.
