Hi,
I have an alternative to Etienne. I solved Andreas problem this way:
[qv qcount] = count_unique(q(1:5));
a(qv)=a(qv)+10.*qcount
Where count_unique is defined as below:
function [ y, count ] = count_unique( x )
if length(x)==0;
y=[];
return;
end;
y = sort( x );
i = find( diff( [ inf; y(:) ] ) ~= 0 ) ;
y = y( i );
if nargout > 1
count = diff([ i(:); length(x)+1 ]);
count = reshape( count, size(y) );
end
It is maybe not so universal (works only on vectors) but I use
count_unique for many similar problems.
