G'day,
I'm trying to read in hourly data from multiple years and create a matrix that incrementally adds each year of data to the same matrix. The code I have is:

j1 = [1975,1977,1978,1979,1981,1982,1983,1985,1986,1987,...
    1989,1990,1991,1993,1994,1995,1997,1998,1999,2001,2002,2003,...
    2005,2006,2007,2009,2010,2011]; %normal years
j2 = [1928,1932,1936,1940,1944,1948,1952,1956,1960,1964,1968,1972,...
    1976,1980,1984,1988,1992,1996,2000,2004,2008,2012]; %leap years

tst=1987:1989;
N=length(tst);
A = NaN*ones(N,8784); %fill with NaNs

for m=1987:1989; % add hourly data
    for j=1:N;
        fname=sprintf('yaq%d.txt',m);
        if any(m == j1);
            data=load(fname);
            Hs=data(:,5);
            A(j,1:length(Hs)) = Hs;
        elseif any(m == j2);
            data=load(fname);
            Hs=data(:,5);
            A(j,1:length(Hs)) = Hs;
        end
    end
end

However, my code seems to be only repeating the last year of data. I know its a simple fix but I'm having a mind block.  What am I doing wrong?

Thanks.
