Why do I receive the error "Attempt to execute SCRIPT sisotool as a function"

I receive the error:

[dpb]

Most likely is you tried to execute a line calling sisotool with a return value...altho we can't see your terminal from here to know exactly what code sequence you did execute to generate the error...attach that code and the error message all in context.

[Walter Roberson]

Not in this case. sisotool is a true function and permits a return value.

Answer 1

[Walter Roberson]

restoredefaultpath
rehash toolboxcache

might solve the problem. If not then command

which -all sisotool

Unless you are using a relatively old release you should see only one entry that is something like

toolbox/control/ctrlobsolete/sisotool.m

If you see multiple entries then the first one might be interfering with the others.
