>> sz=size(Aa) Error using InputOutputModel/subsref (line 44) Subscript no. 2 is out of range.

[John Doe]

Does size work for any other variables, or does it fail for all?

[jasen]

It fails for all. Does another library need to be invoked to use that function ?

[caizheng yang]

It can be solved by restarting the APP or the computer

[Walter Roberson]

You created a variable named size that is of datatype InputOutputModel

This code:

Aa = [0 1 0 ; 0 0 1 ; 0 -2025 -90]
sz=size(Aa)

works fine for me. No error message whatsoever. What are you not telling us? What information have you left out? LIke, did you redefine size? What does this say

which -all size

Does it look like

and so on? Or does it have some function listed that you wrote and is living in one of your folders?
