Hello,

Sorry if this question has been asked before. I tried to find an answer on my own before I came here and was unsuccessful. Here is the story.

I wrote some code and a GUI to work with it. I can call an object called mortFinData just fine. I can also call the method colSwitch within it and pass any two doubles in.

ex. objExample.colSwitch(1,2); works just fine. if dub1 and dub2 are both doubles then objExample.colSwitch(dub1, dub2); works just fine as well.

When I run my gui and I hit a button called switchButton I hit this error:

Cell contents reference from a non-cell array object.

Error in mortFinData/colSwitch (line 361) tempCell = obj.finFile{1,col1};

Error in basicGui>switchButton_Callback (line 1173) linkedObject.colSwitch(switchColOne, switchColTwo);

To try to debug this I had it display switchColOne and switchColTwo before it called colSwitch to confirm they were both doubles. They were.

I don't quite understand where this error is coming from. If anyone could help me out it would be much appreciated.

-John.

Turns out the answer was simple. The error lies in my global variables. It would seem that all of the objects properties were empty :O! I'm going to open a new question if I can't figure out why :P

Apparently obj.finFile is not a cell. Maybe it's a method or an array. Try it with parentheses instead of braces:

obj.finFile(1,col1);

That does not work. I get an Index exceeds matrix dimensions instead. It should still be a cell array. I don't understand why it wouldn't be. Also when referenced directly from the command window the parentheses don't work either.

Thank you for trying though. I can use any help people are willing to offer.
