Creating Matrix with nested loop values

Hello, I am looking for a solution with my problem storing the output of my nested loop into a matrix. The code works perfectly fine and gives me a row for every looped index. For example :

xm =

            2           56           31

xm =

            2           57       24.667

What i want:

All rows together in one Matrix. hours,minutes,seconds are double values format %f

zeit = [hours minutes seconds ];
houra=1;
minutea=1;
houre=1;
minutee=1;
for k=2:3 
for n=1:60   
houra=k-1;
minutea=n-1;
houre=k;
minutee=n; 
x=(zeit(zeit(:,1)>=houra & zeit(:,1)<houre & zeit(:,2)>=minutea & zeit(:,2)<minutee ,:));
xm=mean(x);
end 
end

I hope you can help me.

Answer 1

[a,~,c] = unique(zeit(:,1:2),'rows');
xm = [a, accumarray(c,zeit(:,3),[],@mean)];

Hello, thanks for your help, it works fine for just the (:,3) value but i have a total of 12 i want to mean and store in the matrix.

Hi Peter! For zeit with size [m x 12]:

[m,n] = size(zeit);
[a,~,c] = unique(zeit(:,1:2),'rows');
[x,y] = ndgrid(c,1:n-2);
A = zeit(:,3:end);
xm = [a, accumarray([x(:),y(:)],A(:),[],@mean)];

WOW thank you very much!

Answer 2

[Jan]

zeit  = ???

size1 = 2 * 60;
xm    = zeros(size1, 3);
ixm   = 0;
for k = 2:3
  hMatch = (zeit(zeit(:,1) >= ha & zeit(:,1) < he);
  for n = 1:60   
    ha = k-1;
    ma = n-1;
    he = k;
    me = n;
    mMatch = (hMatch & zeit(:,2) >= ma & zeit(:,2) < me);
    ixm        = ixm + 1;
    xm(ixm, :) = mean(zeit(hMatch & mMatch, :));
  end 
end
