avoid zero value from vector

Hi I have got two vectors from running my matlab code such as

x=[5 0 9 0 4 0 7 0]

y=[0 9 0 7 0 2 0 6]

now i want to use these two vector as input in other code. so i need to avoid these zero values from above vector and my input will be like

 x=[5 9 4 7]

y=[9 7 2 6]

would anyone help me to how can write the matlab code to get above vectors.

Simply use logical indexing:

>> x =[5 0 9 0 4 0 7 0];
>> xnew = x(x~=0)
xnew =
   5   9   4   7
