Many students ask me how do I do this or that in MATLAB. So I thought why not have a small series of my next few blogs do that. In this blog, I show you how to integrate a discrete function.
The MATLAB program link is here.
The HTML version of the MATLAB program is here.

Can I use numerical solution of ODE techniques to do numerical integration?
Yes.
If you are finding the value of the , then we can solve the integral as an ordinary differential equation as
dy/dx=f(x), y(a)=0
We can now use any of the numerical techniques such as Euler’s methods and Runge-Kutta methods to find the value of y(b) which would be the approximate value of the integral. Use [...]
