FOR loop over column vector vs row vector
for-loop, matlab
Solution
when you type
A = [
3
9
5
0];
you create a column vector. Because Matlab iterates over columns you get one answer (the first column). By transposing it you get a row vector with 4 columns and therefore 4 answers each with one column.
Problem
I was just writing a "kinda-foreach" loop in Matlab and encountered this strange behavior: I have the matrix A: ``` A = [ 3 9 5 0]; ``` And I want to use a `foreach` loop (as explained here) on the A. If I write this: ``` for i = A disp('for') i end ``` The result will be: ``` for i = 3 9 5 0 ``` But when I use the transpose, the result will change: ``` for i = A' disp('for') i end ``` Result: ``` for i = 3 for i = 9 for i = 5 for i = 0 ``` Which is the result I want. Can anybody explain what's going on here? What's the difference between these two cases?
