does somebody understand why

diff( ‘test’ )

in my solution 19016 causes this error

it doesn’t in my local Matlab ( 2011a )

apparently it tries to call an overloaded diff ( probably from the symbolic toolbox ) for which it doesn’t have a license

@Martijn: I am not sure why that is happening but in the meantime using "diff(double('test'))" should work fine
