Hello, I am trying to transform a line vector of length x² to a matrix size x*x. For example,
Vector = [1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16]
and I want
Matrix = [ 1 5 9 13; 2 6 10 14; 3 7 11 15; 4 8 12 16]
This is only an example, I am trying to write a function for any vector. Thank you.

Use reshape:
>> V = [1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16];
>> M = reshape(V,4,4)
M =
1 5 9 13
2 6 10 14
3 7 11 15
4 8 12 16
