thanks for that mike.

 

[austinpowers]

actually i am calling a function in my main program twice with different inputs each time.

so i want to know the time taken for two calls.

i tried this

tic
[output1]=function[input1]
toc
time1=toc;

tic
[output2]=function[input2]
toc
time2=toc;

but its not giving correct results ,
i am getting time2<time1

but for my input2 when it goes to that called function it usually takes more time than for input1.so i should get time2>time1

so if i want to know the execution time of a function for two different inputs , is this the right way i am doing
or is there any other way to do this.

if so please let me know about that

"tic" and "toc" do not give you a very accurate measurement (although I think you can control the accuracy to a degree). Of course the execution time also varies depending on what else your computer is doing at the time. Maybe have a play with the "cputime" function.
