Why does length sometimes read the number of columns instead of the number of rows?

Hello, I`m looping over the length of a table (converted to array to be 'double'). However, sometimes the length reads the rows and when run again sometimes it reads columns! Why is this happening? Thanks

length just tells you the longest dimension. If you're talking about a table (the piece of furniture), its length is always its longest dimension. To get just the number of rows or columns, do
rows = size(X,1);
or
cols = size(X,2);

Whenever you have a question concerning a command, start at the documentation:
doc length
There you find these 2 initial lines:
length
Length of largest array dimension
Sounds clear :-)
