Change order in an Array using a second array

I am new in Matlab (sorry)

I have to arrays a= [10, 20, 30, 40, 50] and p = [5, 3, 1, 2, 4]. I am looking a method to change the order of a in function of p (this array is an index vector). For example

newa = [50, 30, 10, 20, 40]

Very basic MATLAB concepts, like how to use indexing, are explained in the introductory tutorials:

https://www.mathworks.com/help/matlab/getting-started-with-matlab.html

Rather than spending time registering on this forum, writing a question, waiting for some random stranger to help you with very basic MATLAB concepts... you can actually learn lots of important and useful concepts yourself simply by doing those tutorials.
