Error using scatter3 (line 45) too many input arguments

I've been using scatter3 for quite a while in some functions and GUIs, and it has been working fine. Today, when I tried to use it, it's giving me the following error:

Error using scatter3 (line45) Too many input arguments

I haven't changed the number of input arguments at all in my functions/GUIs, and it worked before. Additionally, when I use the generic Matlab scatter3 example, I get the exact same error even though the number of inputs is fine.

Any help would be greatly appreciated!

I should also clarify that after getting the error, Matlab will plot a 2D graph (probably ignoring one of the variables?). When I open the scatter3.m file, there are suggestions that a function that checks the number of arguments will be updated in future versions. Could this be causing the issues?

You probably have a variable or other function named scatter3 in your path or workspace.

Type:

which scatter3 -all

in the Command Window. If you get something other than:

C:\Program Files\MATLAB\R2014b\toolbox\matlab\specgraph\scatter3.m

you’re likely overshadowing it.

Unfortunately, I thought this might be the case, but Matlab is using the correct scatter3.

My other suggestion then is to rehash the path:

restoredefaultpath 
rehash toolboxcache

If you’re curious about them, the documentation on them magically appears with these commands:

doc restoredefaultpath
doc rehash

Thank you for the suggestion, but unfortunately it still doesn't fix the issue.

My pleasure. Sorry, though. I’m out of ideas.

It’s likely time to contact Tech Support.
