Integration of discrete data which have a non-linear relationship

In the https://www.mathworks.com/help/matlab/math/integration-of-numeric-data.html documentation page, it is noted that non-linear behavior between the discrete data points being integrated could result in inaccuracy when trapz is used. Is there a better function call to use for such an instance, instead?

Numerical integration based on Simpson's rule provides greater accuracy than integration using trapezoidal rule. Here is an implementation of Simpson's rule from Matlab's Central File Exchange: Simpson's rule for numerical integration
