Hello
I have a given vector x0 and vector a1 of unknown variables. I want to get a new point x1 such that I numerically integrate function fun1(a1,x0) along vector a1 from 0 to 1. If a1 would be a sacalar it would be easy to integrate but it's a vector and I couldn't figure out how to do that. So I would like to ask if there is some function or easier way of integrating that?
Code:
x0 = [0.1; 0.2];
function res = fun1(a1,x0)
res = x0 + (((max(v(a1) - a1' * x0,0)) / (norm(x0))) * a1);
end
function res = v(a1)
res = max(a1(1,1) + a1(2,1) - 1, 0);
end
%x1 = integrate fun1 from 0 to 1
_______________
This is the part of code I'm using. It's only for 2 dimensions for now.
Thank you guys
Any help would be appreciated

Have you looked at quad() or trapz() for numerical integration?

yes i tried trapz,quad,integral... but still couldnt find the solution. Im fairly new to matlab so I started by integrating scalar, which is simple. But I cant get the integration over a vector to work.
