Dear all,
I need to generate different indicators based on the same data but from a set of functions in a loop. Is there a way to specify different functions in a for loop?
Thanks.
Joe

I seem to find a clumsy way myself involving eval:
for ii = 1:length(function_cell{ii})
hhh = eval(['@', function_cell{ii}]); % define a function handle for the ii-th function
zzz = hhh(inputs);
end
If there is any better approach, please let me know. Thanks.

Ran in:
Convert strings-of-function-names to function handles (which they should be anyway):
C = {'sin','sqrt','abs'};
C = cellfun(@str2func,C,'uni',0); % convert
for k = 1:numel(C)
C{k}(-1) % call
end
ans = -0.8415
ans = 0.0000 + 1.0000i
ans = 1

for ii = 1:length(function_cell)
zzz = feval(function_cell{ii}, inputs);
end
