Hello I have the following code:
e = [3 0 -6];
n = length(e);
e_str = cell(1,n);
for i = 1:n
e_str(1,i) = {num2str(e(i))};
end
disp(e_str)
{'3'} {'0'} {'-6'}
I'd like to separete the output with commas as follows:
{'3'} {','} {'0'} {','} {'-6'}

Wondering why you want that. But it can be done as follows:
e = [3 0 -6];
n = length(e);
e_str = cell(1,2*n-1);
for i = 1:n
e_str(1, 2*i-1) = {num2str(e(i))};
if i<n
e_str(1, 2*i) ={','};
end
end
disp(e_str)
{'3'} {','} {'0'} {','} {'-6'}
