4 % independent rows or columns of a matrix A. 5 % RANK(A,tol) is the number of singular values of A 6 % that are larger than tol. 7 % RANK(A) uses the default tol = max(size(A)) * norm(A) * eps. 8 9 s = svd(A); ...
Example 1: Removing All Zero Values Consider a vectornwith some zero values. We want to remove these zeros using thefind()function. clc clear n=[102030];indices=find(n==0);n(indices)=[];n In this example, we start by defining a vectorncontaining some zero values. Thefind()function is...
