Could I name a function "SPHERE" without conflict with the built-in function "sphere"?

"help SPHERE" and "help sphere" produce the same result. Does that mean that Matlab doesn't distinguish between the two?

The answer for the rules on case sensitivity is: it depends.

Yes, you can. To be honest though you could have tested this in less time than it took to ask the question! (Assuming you are familiar with the 'which' function which you should always make use of when you are not sure if you are about to conflict with an existing function name).

I just created a new function called SPHERE and ran the following:

>> which SPHERE
D:\MatlabDev\SPHERE.m
>> which sphere
C:\Program Files\MATLAB\R2016a\toolbox\matlab\specgraph\sphere.m

so both are recognised independently of each other. Calling them both also confirms this.
