Removing zero values from an array

I have an n x 1 array containing values. For exmaple A =

     1
     0
     0
     2
     0
     3

I was wondering if it was possible to create another array except without the zero values. For example

B =

     1
     2
     3

[Stephen23]

A =  [1;0;0;2;0;3]

A = 6×1

1 0 0 2 0 3

B = nonzeros(A) % Introduced before R2006a

B = 3×1

1 2 3

Using logical indexing, you can calculate ‘B’ in one line:

B = A(A~=0)

Thank you so much, can you do the same thing except rather than zeros it says NaN?

[Walter Roberson]

B = A;
B(B==0) = NaN;

[Alice Stembridge]

What I mean't was can I remove the values which say NaN rather than if they contain a zero?

[Walter Roberson]

B = A(~isnan(A));

Thank you Walter.

I was away for a few minutes with another Answer.

[Clemens von Szczepanski]

you can use R = rmmissing(A) now :)
