Reassigning values in a matrix

I have a matrix, and here's what I want to do with it -

1.) Find the max value of the matrix, assign it to be 1.

2) Find all the values in the matrix that are 80% of the max value, and assign it the value 0.8

3) Find all the values in the matrix that are 60% of the max and assign it the values of 0.6

How can I do this in matlab?
