Hello!
I would like to vectorialize a subroutine calculating an integral.
The main entry is an array that includes, in row, parameters of the function to integrate and the boundaries for the integration.
It works fine when called into a for loop, but I failed to vectorize it using arrayfun. Below is the code.
Any help to speed up this code would be most the welcome!!!
Many thanks
Olivier
function hV=change_potential_by_history_NoDOV3(t,t0,tpeak,w,past,slops,extrems)
%Matlab2022
parfor i=1:length(t)
int(i)=integrate_PSP(t(i),t0(i),tpeak(i),w(i),past(i));
end
%I WANT SOMETHING LIKE
%int=arrayfun(@integrate_PSP, t,t0,tpeak,w,past)
%
hV=sum
end
function int=integrate_PSP(t,t0,tpeak,w,past)
if t>t0
tr=t-t0;
if tr-past>0
int=integral(@(tr) w.*tr.*exp(-tr./tpeak),tr-past,tr)/past;
else
int=integral(@(tr) w.*tr.*exp(-tr./tpeak),0,tr)/tr;
end
else
int=0;
end
end
