Hello, I am trying to evaluate the number of rows of a certain matrix 'Conn' using
d = size(Conn,1)
If I initialise the matrix from an empty workspace like this
Conn = [1 2 3; 4 5 6]
the command displays the correct answer
d = 2
When using the exact same command inside a bigger script, I get this error message:
Subscript indices must either be real positive integers or logicals.
Anybody has a clue?

You have a variable names size.
Rename this variable and clear it.

Looks like the most obvious answer usually is the correct one. Thank you so much, I was gonna get crazy on this!
