less time to run how
显示 更早的评论
%% i am using this and it take long time to run,
F_half=integral(fun,0,inf,'ArrayValued',true,'RelTol',1e-4)
%% if i use this F_half=integral(fun,0,inf) then it take less time
%% as i am using this F_half=integral(fun,0,inf,'ArrayValued',true,'RelTol',1e-4) type function many times and that take too much time why and how can i colve it
%% and what is the use of 'ArrayValued',true,'RelTol',1e-4

Usually, fun is called for a vector of x-values and must return an array of the same size. ArrayValued = true forces "integral" to evaluate your function only for one single x-value at a time. This causes longer run times.
