Repetition of element in matrix

Suppose i have a matrix A=[23 17]

I want to proportion element of A in such a way that sum will remains equal to elemental value of A.

E.g 23 can be proportion to 8 8 7 . Similarly 17 can be 7 7 3

Hence final matrix will be B= [8 8 7 7 7 3]

I am trying to use repelem function but it requires equal proportion of elemets.

How to generate B matrix?

If you are looking for random values, then see https://www.mathworks.com/matlabcentral/answers/327656-conditional-random-number-generation#answer_257296 which has code written by someone who put a lot of thought into making the process "fair"

Actually i have a proportion matrix P by which i have to proportion the elements. This proportion will have all equal element except last element.

E.g P=[3 4]. Now 23 to be divided in 3 proportion of which 2 proportions are to be equal, so it will be 8 8 3. Similarly 17 will be divided by 4, then it will be 5 5 5 2.

hence final matrix B=[ 8 8 3 5 5 5 2]

Can you suggest how to generate code for matrix B?

I already posted complete code.
