'spy' command

'spy' command

'spy' command

(OP)
Hi there. I met a problem when working with matrix and cell. Assume
that I have two matrices which are obtained from 'spconvert' command. Let
it be:

         load cflinder.dat;
         A{1}=spconvert(cflinder);
         load cadelai.dat;
         A{2}=spconvert(cadelai);

To be careful ^_^ I invoked 'cell2mat' command to A(1) and A(2). After
all, I typed:

         G = blkdiag(A(1),A(2))
         cell2mat(G)   (*)

Actually, (*) is optional (call it or not) and I received the same
error for the 'spy' command:

         ??? Function 'find' is not defined for values of class 'cell'.

         Error in ==> find at 39
             [varargout{1:nargout}] = builtin('find', varargin{:});

         Error in ==> spy at 55
         [i,j] = find(S);

What happens to me? I think that G is not a cell array but it keeps
telling errors like that. Please provide some helps/hints/ideas to my
problem. Thank you very much.

RE: 'spy' command

What language are you using?

I am using Matlab, sorry ^_^

RE: 'spy' command

Then why wouldn't you post this in the Matlab forum?

TTFN
