find local max in time window

am trying to find the local max in time window , i know that I have to define part from the signal then use the findpeaks built in function then take the max value of it.

    % code
pks_value=[];this to store the max value from the peaks
step=200;
pcg=pcg_lp2';
for i=1:200:N
    temp=pcg(i:i+step);
    [pks,locs] = findpeaks(temp);
    pks_value(i)=max(pks);

end

it give me the error msg "Index exceeds matrix dimensions. " so how to fix it , what to change

Answer 1

If you have a recent copy of MATLAB, try using movmax().

[Hasan alomari]

it will give the max value but without the location

[Greg Dionne]

This should get you started:

x = randi(10,150,1);
tmp = movmax(x,5);
imvmax = find(x==tmp);
mvmax = x(imvmax);
plot(1:length(x),x,'-',imvmax,mvmax,'o')

Answer 2

thank you i did it using the max which also return the value and the location, but will try this also to see if I will obtain the same result
