Using nested loop to check for whole numbers inside a matrix

Im trying to find any values that are not whole numbers inside a 3x3 matrix, but i have to used nested loops

This my code

x=[1 2.5 4;3.2 6 9;5.2 6 7]

w=mod(x,1)~=0; %checking for whole numbers in the matrix

d=x(w); %this are the values that failed the whole number test

[r,c]=find(w); %location of those values

How would i used nested loops to check every value in the matrix for values that are not whole numbers?

Why do you want to use loops, you have just solved it in a more efficient way?

To check for whole numbers inside a matrix using nested loop, use the code as shown below.

x = [1 2.5 4;3.2 6 9;5.2 6 7];
[rx,cx] = size(x);
for i = 1:rx
    for j = 1:cx
        w(i,j) = mod(x(i,j),1)==0;
    end
end
[r,c] = find(w);
