Im currently modifying an algorithm which randomly samples a given matrix by
% Omega - set of observed entries. Should be linearly indexed.
%
% A - data vector of the form M(Omega)
[m,n] = size(M);
I = randi([0 1],m,n);
Omega = find(I);
A = M(Omega);
I wonder is it possible to replace the omega by a mask image which is made of text intead of randomly generating it.

Omega in the above line of codes is a inde, it should be logical/ double. How you can take a text?
