Find the Built-In functions and Toolbox functions in either a string or a function handle.
Generate a string of alphabetized Built-In functions followed by alphabetized Functions.
Inputs:
fh=@(x)log10(x)+log2(x)+abs(x)
str='smooth3(x,y)-filter(x)+abs(n)+filter2(u)+sin(x)+numel(z)'
Outputs:
'abs log2 log10'
'abs filter numel sin filter2 smooth3'

Richard: I believe there are a couple of inconsistencies in the test cases.
- You mention in the problem statement that the 'alphabetized built-in' functions should follow 'alphabetized' functions. However, 'log10' (not built-in) appears before 'log2' (built-in).
- 'i' is also a built-in function. 'which i' indicates that.
'i' in test case 2 is also 'built-in'
I agree , exist('i') return 5 .
I changed hte "i" to "k".
Even though "i" was being used as a variable and not in its capacity as a built-in function.
In what order the names of the function are sorted?
(Thanks for the useful tags.)
The functions are sorted alphabetically and by type.
Ex. [built_in_alphabetical, toolkit_alphabetical]
