MATLAB cannot call or index into a temporary array in for loop

Hello Friends,

Here is my code:

 M = {'a', 'b', 'c'};

for i = length(M)
    M(i) = M(i)(M(i)~=0);    
end

In other words, I am trying to get for each vector 'a', 'b', and 'c' the following in for loop:

a = a(a~=0);
b = b(b~=0);
c = c(c~=0);

I get the following error: "cannot call or index into a temporary array"

I will appreciate any advice.

I don't know what you want, your example is not appropriate, comparing letters with 0!

A=[1 2 0 5 0 7]
B=A(A~=0)

I have a cell array, and I want to remove 0 entries from M. I want to do it for each 'a', 'b' and 'c' in for loop. In other words, it will be

a = a(a~=0);
b = b(b~=0);
c = c(c~=0);
