Question

[EDIT: Tue Jun 7 04:51:14 UTC 2011 - Reformat - MKF]

I'm working with a Lvq network, I want to have the error in the classification, but the code send me this error

??? Undefined function or method 'rdivide' for input arguments of
type 'cell'.
Error in ==> RedesLVQ at 54
PercentS = (Err./n)*100;

*This is the part of the code: *

y = net(P);
%Y = sim(net,P);
perf = perform(net,y,t)
classes = vec2ind(Y)
[a b c Err, perf]= sim(net,P);
[m,n] = size(P);
PercentS = (Err./n)*100;

The documentation shows that sim returns cell arrays for E.

It is not clear to me that dividing by the number of time steps and multiplying by 100 is going to get you any kind of meaningful percentage, but...

PercentS = cellfun(@(C) C .* (100 / n), Err);

This will return a cell array of arrays of values. I will leave it to you to assign meaning to those values.
