If you have a regular legal installation of MATLAB; svd() should be present.

If it is not, what is the output from the following?

which -all svd

If nothing shows up, try:

restoredefaultpath; rehash toolboxcache

If that doesn't work; contact technical support.

thanks for your reply, below are the answers. I want to decompose an image, which should i select from and how do i call the function? thanks

built-in (C:\Program Files\MATLAB\R2010a\toolbox\matlab\matfun\@single\svd)    % single method
built-in (C:\Program Files\MATLAB\R2010a\toolbox\matlab\matfun\@double\svd)    % double method
C:\Program Files\MATLAB\R2010a\toolbox\distcomp\parallel\@codistributed\svd.m  % 
codistributed method
C:\Program Files\MATLAB\R2010a\toolbox\robust\robust\@frd\svd.m                % frd method
C:\Program Files\MATLAB\R2010a\toolbox\symbolic\symbolic\@sym\svd.m            % sym method

MATLAB will automatically select the correct function depending on the datatype of the input. Usually that would be the one marked as "double method".

i have tried call that function using [u,s,v]=svd(a) but it has always given me error saying invalid function or method svd.

What does class(a) show ?

hi, thanks much, it now working.

How did you solve the problem?
