(I'm a beginner of matlab. )
I try to make a matlab sub-function to analysis the frequency of our lab data,however,matlab always display "Not enough input arguments."
I can't fix error of my program.
What should I add or change?
function f = freq(time,data)
t = time;
d = data;
max = islocalmax(data);
dmax = d(max);
tmax = t(max); %the t of vmax
for i = 1 : length(dmax)-2
period(i) = tmax(i+2) - tmax(i);
end
f = 1/mean(period);
end

time = ... some values
data = ... some values
f = freq(time,data) % this is how you call a function
Google "how to call a function MATLAB?"
Note: Don't use max as variable name because MATLAB has an inbuilt function named max()

https://in.mathworks.com/help/matlab/math/parameterizing-functions.html - the link shows you how to parameterize a function , plus you need to call the function properly with passing in the adequate amount of arguments to the function as shown in the answer above. Don‘t use global!, it’s completely avoidable.
