MATLAB: “Undefined function or variable ‘imsplit’.”

Question

I am using Matlab 2015a and it says "Undefined function or variable 'imsplit'." when I run my code. Is this function not deifned in matlab 2015a ? If not, what is the best alternative for "imsplit" in 2015a ?

Also, I have been coming across so many functions that I found undifined in 2015 that are actually released in other versions. Is there a place I could find all of them at one place ?

Requires R2018b

You should be using the "doc" function in your MATLAB release to find the functions available in your release.
