o=4;
m = ['c','d','c','f','e','c'];
oo=o.*ones(1,length(m));
q=zeros(1,length(m));
w=zeros(1,length(m));
for i=1:length(m)
q(i)=strcat(m(i),num2str(oo(i))); %here is where the error happens
w(i)=eval(q(i));
end
I know that eval function is not recommended but I'm trying something with my code and it doesn't have to do anything with the error (until now atleast)

I hesitate to even answer this question. The use of eval is a bad idea. Do not do that. eval can almost always be avoided and your code doesn't look like an exception.
The reason for this error is that you are trying to store multiple chars in a single position. You need to either use strings (use double quotes), or you need to adapt the indexing for q, or replace all occurrences of q(i) with q.
