Hello, I just start coding in Matlab and I would like to calculate probability number. f.e
A=[1 7 1 2 8 8 6 3 7 7]
then, I would like to know probability of number 8 or 6 etc. "A" could be array for example.
Is any function for this or is possible to use any simple loop to find this.
Thank you.

Hi,
You can count number of element equal to a particular number in a vector/matrix using nnz and equality condition. For above query you can find first for 8 and then for 6 and add the two and divide by total number of elements in a vector/matrix.
numOf8 = nnz(A==8);
numOf6 = nnz(A==6);
probOf8or6 = (numOf8 + numOf6)./numel(A);
