Basic functions for using matrix approach for distributed-order differential equations, and demos.



View License

This submission contains the basic functions that are necessary for using the matrix approach to discretization of distributed-order differential equations, and demos.

It provides the Matlab code from Appendices 4-6 to the following book:

The code from Appendices 1-3 can be found in FEX submission #36574 "Demos for investigating distributed-order linear time-invariant systems" by Zhuang Jiao (

The matrix approach for differential equations with fractional-order derivatives in the case of constant orders of derivatives is described in the following articles:
