Handle References and Structure

I am trying to decode a script someone else wrote. I am getting a "bad cell reference" error message on the following:

handles.r = handles.NonNaNIndices{handles.IntTable,1}(handles.loop,1);

Any help or direction is appreciated.

K>> class(handles)

ans =

struct

K>> class(handles.NonNaNIndices)

ans =

cell

K>> size(handles.NonNaNIndices)

ans =

     2     1

Thanks.

Hmm.. Okay, what is handles.IntTable at that point?

[David]

K>> handles.IntTable

ans =

     1
     2

Because your IntTable has multiple entries, your

handles.NonNaNIndices{handles.IntTable,1}

is expanding to multiple outputs, and you are then trying to use () indexing on those multiple elements; you can only use () indexing if the {} expression expands to a single element. You need to decide what output you want in this situation.

At the command line give the command

dbstop if error

and then run the program. When it stops, please show

class(handles)
class(handles.NonNaNIndices)
size(handles.NonNaNIndices)
