combining lots of vectors of unequal length

i have: a=[1 2 3 0 0] b=[4 5 6 7 0 0 0] c=[8 9] i want: d= [a b c] with zeros removed d=[1 2 3 4 5 6 7 8 9]

Is there a generic code for this? because i have lots of vectors like a,b and c and their length is very large and unequal

I don't think there is a generic code. How about making a function to do this, like:

function [d1,d2] = yourFunction(a,b,c)
d1 = [a,b,c];
idx = d1 == 0;
d2 = d1(~idx);
end

Here is an example.

>> [d1,d2] = yourFunction([1 2 3 0 0],[4 5 6 7 0 0 0],[8 9])
d1 =
   1     2     3     0     0     4     5     6     7     0     0     0     8     9
d2 =
   1     2     3     4     5     6     7     8     9
