5Matrix 1-Norm
Purpose 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.
