Function inside a for loop

Hi,
I have a function that works well when I called it one by one.
>>Calculate(a,cs,sclk)
ans: 20
>>Calculate(a,cs,sclk)
ans: 20.5
>>Calculate(a,cs,sclk)
ans: 20.25
However, when i switching the function inside a for loop, it kept produced the same answer.
for j=1:9
d=Calculate(a,cs,sclk);
fprintf('value %d is %d\n',j,d);
end
Asnwer:
value 1 is 10
value 2 is 10
.
.
.
value 9 is 10
And I called it in a series. They all produced the same answer.
>> d1=Calculate(a,cs,sclk);d2=Calculate(a,cs,sclk);d3=Calculate(a,cs,sclk);d4=Calculate(a,cs,sclk);
Ans:d1=15,d2=15,d3=15,d4=15,d5=15
Anyone know what's happened for my function here?

You can measure time with tic and toc.
Please have a look at:

For loop will be executed in a matter of milliseconds. On the other hand when you call function once at a time, there is a significantly more time difference between calls. So perhaps your input parameters cannot change fast enough in the loop call.
