This took me 3 days but I am old and slow.

Work through, modify, play with and understand the examples given in the Matlab documentation about Nested Functions.

My solution is adapted from their second example: makefcn.m.

Test	Status	Code Input and Output
1	Pass	noOp = @(x)x; fh2 = iterate_fcn(noOp, 50); assert(isequal(fh2(pi),pi));
2	Pass	addOne = @(x)x+1; addTen = iterate_fcn(addOne, 10); assert(isequal(addTen(3),13));
3	Pass	addOne = @(x)x+1; addOne2 = iterate_fcn(addOne, 1); assert(isequal(addOne2(3),4));
4	Pass	squarer = @(a) a^2; fh2 = iterate_fcn(squarer, 3); assert(isequal(fh2(3),6561));
5	Pass	fh = @(y)sqrt(y+1); fh2 = iterate_fcn(fh,30); assert(abs(fh2(1) - (1+sqrt(5))/2) < 100*eps);
