MATLAB: Class definition @ directory error

Question

Hello,

I am writing a script wherein a new class 'polynomial' is defined. When I run the script, I get the following error:

 Error: File: polynomial.m Line: 49 Column: 10
A class definition must be in an "@" directory.

Upon typing which('polynomial'), I get the following output:

 /home/..../multipoly/@polynomial/polynomial.m

Clearly, polynomial.m is in a directory called @polynomial, but I'm still getting the error. I'm quite confused by this. I am running 64bit R2012a on Ubuntu 12.04.

Any help would be appreciated. Thanks.

Answer 1

I assume that

• you created the folder "/home/..../multipoly/@polynomial"
• you created the file "polynomial.m"
• the keyword, "class" appears in the file "polynomial.m" (line 49)

Do you try to use old or the new Class-Definition Syntax; do you use the new keyword classdef?

Did you try

    which('polynomial','-all')
