How to check number of zeros in an array?

334 views (last 30 days)
Eg: I have a vector A = [0,0,4,3] and B = [0,1,2,3,4] and C = [0,0,0,0,0] and D = [0,1,2,0,0]
SO THE OUTPUT SHOULD CONTAIN NUMBER OF ZEROS IN EACH VECTOR:
A = 2
B = 1
C = 5
D = 3

A = nnz(~A)
B = nnz(~B)
C = nnz(~C)
D = nnz(~D)

I doubt that it gets much more compact than that!

Try this:
nzeros=numel(A)-nnz(A)
numel(X) give you the number of elements in an array, nnz(X) give you the numbers of Non zero elements in an array.
try it for every array you have.
