MATLAB: Delet zeros after final number

matrix

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,

Best Answer

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

   a=[    0     0    10   150   150     0   125   150     0    10   125   150
       0     0    80     0     0    70    80    55    70    80    80    55]
   out = unique(a.','rows')'

add

a0 = unique(a.','rows');
t = ismember(a0(:,1),a0(size(a0,1),1));
a0(t,2) = sort(a0(t,2),'descend');
out = a0.';

Please read about functions unique, size, ismember, sort.

There are two solutions:
