can someone assist me? i am trying to use the matlabs svd function but it returned an error
"?? Undefined function or method 'svd' for input arguments of type 'double' and attributes 'full 3d real'.".
here is part of the code i was working on:
F=imread(irisFileName); G=im2double(F);
%perform singular value decomposition
xpattern=svd(G);
P=[xpattern' str2num(irisFiles(i).name(1:3))];
T=[T;P];
irisFileName
[size(P) size(T)]
end
end
thanks

svd() only works on a 2-D matrix, although I'm surprised by your error message.
I would have expected:
"Error using svd Input must be 2-D."
You are using the MathWorks' svd() function, correct?
If you enter,
>>which svd
you get back some path like:
...matlab\matfun\@single\svd

You are probably trying to do svd on an RGB image. You probably need to use rgb2gray() to convert it to grayscale.
