Error in using MNPBEM toolbox

When I am using MNPBEM toolbox by UNI GRAZ, and running the samples, errors always come as "Too many outputs requested. Most likely cause is missing [] around left hand side that has a comma separated list expansion." Is there anyone who can help? Thanks!

Please show the complete error message.

Same as me too,

Index exceeds matrix dimensions.

Whatever enei is, the object exc is not as large as that in some respect.

This is not related to the original question about too many output arguments.

Hi,

I had the same problem, for me it was related to the function subclasses found in /MNPBEM14/Misc/+misc/subclasses.m In order to find the subclasses more efficiently, it only searches on folders with the name MNPBEM. If you don't add the MNPBEM folder in the path, but only its contents (that's what I did), it won't find any MNPBEM-named folder and it will subclasses will return an empty struct, creating the error you mention.

Just add the whole folder to the path and it should be solved (not only what's inside, but the folder itself too).

Best,
