Sorting and replacing data in matlab
I have a position Array suppose "A" A =[ 1, 0, 3, 4, 5, 6, 7, 8, 0, 0,15, 20, 10, 9]. I want to replace all those values of A which are grater than 5. Here, the first element (in A, it is 6) which is grater than 5 will be replaced by a constant say c1 Then next element (in A, it is 7) which is grater than 5 will be replaced by a constant say c2 =c1+ a, where 'a' is a constant After that the next element (in A, it is 8) which is grater than 5 will be replaced by a constant say c3 =c2+ a, where 'a' is a constant ...... So on. I want to see the final Array like this A =[ 1, 0, 3, 4, 5, c1, c2, c3, 0, 0, c4, c5, c6, c7]. N.B. if any element of A is less or equal than 5, the elements of A will be unchanged

Here is a vectorized alternative:
A = [ 1, 0, 3, 4, 5, 6, 7, 8, 0, 0,15, 20, 10, 9]; a = 1; c1 = 10; idx = A > 5; A(idx) = c1 + (0:nnz(idx)-1)*a;
Result
>> A
A =
1 0 3 4 5 10 11 12 0 0 13 14 15 16
