how to remove the zeros from matrix x??
clear all
clc
n=1;
m=1;
z=randi([1 10],5,10)
for i=1:5
if(mod(i,2)==0)
for j=1:length(z)
if(mod(j,2)==0)
x(m,n)=z(i,j)
n=n+1;
end
end
m=m+1;
end
end

Depends on what you mean by "remove". A matrix cannot be anything but a rectangular array, so you simply cannot "remove" elements leaving "holes" in a regular array. A cell array also has to be regular, but it does have the feature that a cell may contain the empty indicator. For a regular numeric array, you can use NaN or Inf as missing value indicators, but you can't not have something in every location.

If all you want is the intersection of all even rows and columns, just use indexing.
z = randi([1 10],5,10)
x = z(2:2:end,2:2:end)
FWIW, the reason your code doesn't work is because you never reset n
