'spy' command

[Vagabon]

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.

I am using Matlab, sorry ^_^

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