countsumunique

I have a matrix
A = [
1 2 3 0 0;
2 2 0 2 1;
1 0 2 3 1]
I want to count column wise frequency of occurrence of all non zero numbers, i.e. 1, 2, 3 So as to get result in form of
First Col   1 (2)    2(1)    3(0)
Second Col  1(0)    2(2)    3(0)
Third Col  1(0)    2(1)    3(1)
Forth Col  1(0)    2(1)    3(1)
Fifth Col  1(2)    2(0)    3(0)

Best Answer

>> [N,C] = hist(A,0:3);
>> Z = N(C~=0,:).'
Z =
   2   1   0
   0   2   0
   0   1   1
   0   1   1
   2   0   0
