I need to extract zeros from a vector while keeping the same order of elements in s.

Like this :

S=[1 0 0 2 3 0 0 0 2 1 0 4 0 0 0 0 1 0 2]

S1=[1 2 3 2 1 4 1 2]

在 MATLAB Online 中打开

>> S=[1 0 0 2 3 0 0 0 2 1 0 4 0 0 0 0 1 0 2]
   S =nonzeros(S)'
S =
    Columns 1 through 13
       1     0     0     2     3     0     0     0     2     1     0     4     0
    Columns 14 through 19
       0     0     0     1     0     2
S =
       1     2     3     2     1     4     1     2
