How do I get rid of this path error message?

I keep getting the message error: ??? Undefined function or method 'ret2price' for input arguments of type 'double'.

I did not create this function- it comes standard with Matlab.

Any ideas how to fix it?

Thanks,

ret2price is part of the Econometrics Toolbox. Do you have this licensed/installed?

running:

ver

at the command line to tell you if it's installed.

Either you do not have the Econometrics toolbox installed, or do not have it licensed, or your version predates that function, or else your installation is corrupt and the file is missing.
