read an array and output at intervals

Hi,

I need to output 'out' as shown below using a MATLAB script. I want every year 106th row to read and output. Following script won't do this. Can someone help in this regard?

out=prcp(106:365:end,1:2);

out=1998106  0
    1999106  13.2
    2000106  0 
    .
    2013106  0

 prcp=  1998001     0
        .
        .
        1998106     0
        .
        .
        1999106     13.2
        .
        2013106    0

What is it that you want? I cannot tell from the description.

I want 'out' as shown using 'prcp'. prcp is a 5502x2 matrix. Need to read every year 106th row.

e.g. 1998001 1998 is the year and 001 is the day (Jan 01) and so on.

mask = (mod(prcp(:,1),1000) == 106);

out=prcp(mask,:)

if you want to also include "1998001 0", (apparently the first row) then

mask = (mod(prcp(:,1),1000) == 106);
mask(1)=true;  
out=prcp(mask,:)

Thanks a lot. This is what I wanted.
