I have a symbolic expression in 3 variables f(r,z,t). I am trying to factor it such that I have an expression of the form:
f(r,z,t)=g(t)*h(r,z)
I am using R2014a fyi. I think this can be done with factor(f,t) if I had R2016 but is there a nice way to do this with R2014.
Thanks
Drew

factor() has always been part of the Symbolic Toolbox.

I'm trying to figure this out as well. I see
C:\Program Files\MATLAB\R2020a\toolbox\matlab\specfun\factor.m
C:\Program Files\MATLAB\R2020a\toolbox\shared\hdlshared\@hdl\factor.p % hdl method
C:\Program Files\MATLAB\R2020a\toolbox\symbolic\symbolic\@sym\factor.m % sym method
when typing
which -all factor
It keeps defaulting to the first function when I'm trying to call the third. How do I get around this?
