Concatenate Three Row Vectors into an Array in a For Loop

1 view (last 30 days)
What is wrong with my code?
Z=[3 8 2 4];
for i=1:N
I want to have F(i)=[B(i); C(i); D(i); E(i)] that way I can have a matrix with all the values of B(i), C(i), D(i), and E(i) obtained in the for loop.
However, I am getting this error message:
Error in sym/subsasgn (line 700)
S = builtin('subsasgn',[],S,zeros(size(B)));
Error in Program_1 (line 30)
V_total(i)=[VA(i); VB(i)]
How do I fix my code?

Well, you didn’t actually show us the code that is throwing the error in the context of the loop it may be in, but I would change the subscripting to:
V_total(:,i)=[VA(i); VB(i)];
That adds a column to V_total for each iteration of the loop.
