Store occurrences of an array in an equal sized array

Good morning,

I would like to count the occurrences of all the elements of an array generating a new array that stores the value in the corresponding cell. (Matlab R2018a)

Here is an example of input, output:

Input = [1 2 3 3 4 5 5;
             2 4 5 1 2 3 4;
             1 1 2 2 3 3 5]

Output = [ 4 5 5 5 3 4 4;
                 5 3 4 4 5 5 3;
                 4 4 5 5 5 5 4]

Thank you very much.

[~,~,c] = unique(Input);
Counts = accumarray(c,1);
Output = Counts(Input)
