How can I use visdiff correctly?

Question

Charlie 2012-8-27

Hi,

I am trying to use visdiff to compare different version of a code. The script fails with an error.

If I use the GUI dialogue, I get the error:

Undefined function 'comparisons_private' for input arguments of type 'com.mathworks.comparisons.source.impl.LocalFileSource'.

or if I use the command

visdiff('river_reduced_gravity.m','temporary_2012_08_24_reduced_river_gravity_recheck.m')

I get the error:

Undefined function 'comparisons_private' for input arguments of type 'char'.

What am I doing wrong?

Thanks, Charlie

Hi,

sounds like a messed up ML search path. Try running:

restoredefaultpath;
matlabrc

After that try again. Normally the comparisons_private is a function shipped with MATLAB:

>>which comparisons_private
C:\Program Files\MATLAB\R2012a\toolbox\shared\comparisons\comparisons_private.m
