I have a large column vector (col1) I have the following code:
notcontacts=(col1(:,1)>600);
col1=col1.*notcontacts
Now I want to to delete all of the zeros that are in the column of data so i have the following (col2) which is only made up of the values that are greater than less than 600.

I am sorry, typo... I want a column (col2) of numbers that are less than 600. Ex:
col1=[0 0 456 245]
then after column manipulation I want:
col2=[456 245]

I meant to say less than 600 not "greater than less than"

EDITED
idx = idx = col1(:,1) < 600 & col1(:,1) ~= 0;
col2 = col1(idx, 1);

@Oleg : You forgot the removal of zeros:
idx = col1(:,1) < 600 & col1(:,1) ~= 0;
