k-Wave

   I installed the k-wave toolbox using MATLAB 7.10.0 and without changing anything attempted running both of these example scripts. Both of them threw the same error in the "smooth" curve-fitting function used by kspaceFirstOrder2D function that stated:

   ??? Error using ==> smooth at 131
   X and Y must be the same length.

   Error in ==> kspaceFirstOrder2D at 428
   source.p0 = smooth(kgrid,source.p0,true);

   Reading through the help guide it doesn't look like anything needs to be adjusted for these scripts to run properly. Am I missing something or is this a bug due to MATLAB version compatibility? Thanks.

   This sounds like an error thrown by the smooth function which is part of the curve fitting toolbox (not the smooth in k-Wave; unfortunately the functions have the same name although we may change this in a future release). Do you also have this toolbox installed?

   This suggests the k-Wave toolbox may not be correctly installed, although MATLAB obviously found the simulation functions OK so that is puzzling. What happens if you type help smooth at the commmand line? Can you see the k-Wave entry under the contents in the MATLAB help browser?

   We have tested k-Wave on most MATLAB versions since 7.5 so it shouldn't be a version issue.

   I think it may have been an installation error. After re-installing it seems as everything is fine. Not sure why it was throwing an error in the curve fitting toolbox, however.
