digitrevorder vs bitrevorder?

Apparently both commands are doing same job of reversing input but what is difference between both?especially in regards to applications? In which application scenarios do we use bitrevorder and in which scenarios do we use digitrevorder?

Digitrevorder and pemuterevorder have quite different functionalities.

digitrevorder is to permute data into digit reversed order whereas bitrevorder is used to permute data into bit reversed order.

Example :

a=(0:15)';
y=bitrevorder(a)
b=(0:8)';
z=digitrevorder(b,3)


%Output
y =

     0
     8
     4
    12
     2
    10
     6
    14
     1
     9
     5
    13
     3
    11
     7
    15


z =

     0
     3
     6
     1
     4
     7
     2
     5
     8
