MATLAB: Hello, I am trying to do a numerical integration on a function with limits from 0 to infinity, is it possible

Question

Say I wanted to numerically integrate this function:

f(a) = 0.25*exp(-0.25*a) from 0 to infinity. Can the trapezoid or Simpson rule, or any other numerical integration method work in Matlab to complete this?

Thank you

Answer 1

integral() can handle it, as could the older quadgk() .
