MATLAB: Find a Maximum in a Matrix

functionmatrixmaximamaxima in matrixmaximum

Hello all,
I am trying to find a maximum in a 484×1800 matrix. Particularly i´d need the index of the maximum of each row.
The result should be a 484×1 vector or 1×484 with the index of each maximum on each place of the vector.
I tried a few things with find and max and max(abs…. but it seems that the subscription in a matrix does not fit with these functions.
Please help,
Thanks,

There probably is a more elegant solution but this should work
a=rand(40,10);   %some random 40x10 data
for i=1:length(a)
    [~,c(i),~]=find(a(i,:)==max(a(i,:)));
end
values=max(a,[],2);
% this is the largest value in each row and its position in the row
output=[c' values]
