Dear all, I'm looking for an efficient way to delete zeros after final number in MATLAB,
A= [ 5 6 0 3 2 0 9 0 0 0 0 0 0]
B = [ 5 6 0 3 2 0 9]
Thank you so much,

Technically speaking, zero is also a number...

A=A(1:find(A,1,'last'));

There are plenty of ways to do that. For instance, find(A) will find indexes of all nonzero elements. So you can write:
B= A(1:max(find(A)))
max(find(A)) - index of the last nonzero element in A
