Hi, I have 3 different cell arrays like below - same size (let's call them A, B and C): That I need to evaluate in an if statement in a for loop. But the final result gives me several empty numeric array in couple of the cells. The code is:
for i=1:4
for j=1:4
for k=1:10
for r=1:10
if ((abs(A{i,j}(k,r)))/(abs(C{i,j}(k,r)))<1) && ((abs(A{i,j}(k,r)))/(abs(B{i,j}(k,r)))<1)
A_num{i,j}{k,r}='Point is stable: Category 1 is assigned';
elseif ((abs(A{i,j}(k,r)))/(abs(C{i,j}(k,r)))>1) && ((abs(A{i,j}(k,r)))/(abs(B{i,j}(k,r)))>1)
A_num{i,j}{k,r}='Point is unstable';
end
end
end
end
end
For example, one of the cell array result is like bleow: I checked all the components of the original cell arrays and none of them are zero or inf. Am I doing something wrong here?

The && are ‘short circuit’ AND operators. The second expression (after the &&) will not be evaluated if the first expression is false.
If you want to evaluate both of them, just use & instead.
