Problem 582. Function composition - harder
Write a function that accepts an arbitrary number of function handles f_1, f_2, ..., f_n and returns the composition h. That is,
h = (f_1 o f_2 o ... o f_n)(x) = f_1(f_2( ... f_n(x) ... ))
Example:
>> f1 = @(x)x+1; >> f2 = @(x)3*x; >> f3 = @sqrt; >> h = composeFcn(f1,f2,f3); >> h(9) ans = 10
because 3*sqrt(9)+1 = 10.
You can assume that there will always be at least one input passed to the composeFcn function.

"compose" is a built-in Matlab function.
Please, change the function name in the test suite, since no new solution is allowed.
Composition is in reverse. Apply last function, then next-to-last, and so forth to first.
