Time consumed by a function in a code

I have made an equivalent function of variable fractional delay and running it with a for loop and with the other functions like xcorr in the code. I have to find the time taken by the code in executing the equivalent function only and not the xcorr function. I have used tic toc, but it gives the time for the whole code.

Read about profiler. You can use tic toc.

t1 = tic ; 
val = myfunction(inputs) ; 
t1 = toc(t1) ;

Yes I have used tic toc.

I have a for loop and inside that I have alternate vfd function and xcorr, I just have to check the time consumed for alternate vfd function.

[KSSV]

N = 10 ; 
t1 = zeros(N,1) ; 
t2 = zeros(N,1) ; 
for i = 1:N
    ti = tic ; 
    val = vfd(input) ;   % your function
    t1(i) = toc(i) ;
    
    tj = tic ; 
    val = xcorr(input) ; 
    t2(i) = toc(tj) ; 
end
plot(1:N,t1,'r',1:N,t2,'b')

Also read about profiler.

there are two loops with vfd function and the time is growing as I am increasing the loop

This gives an error TOC must be a uint64 scalar. Please resolve.
