how do I write a for loop that calls a function for each output value of another function?

I wrote two functions, one of them needs to contain a for loop that calls another function for each output value [M]=FirstFunction (lowValue,highValue) inside this function i need to write a for loop that loops through all outputs of the second function inside a specified range. the second function is [A,B,C]=SecondFunction(SingleValue) how do i write the for loop? i am a biginner in matlab ! Your help is a appreciated !

   [A, B, C] = SecondFunction(SingleValue);
   for K = 1 : numel(A)
     this_A = A(idx);
     do_something(this_A);
   end
