Merging Unique Cell Array Elements
显示 更早的评论
I have a cell array with non unique elements and an array with corresponding integer values. I'd like to combine all the repeat cell array values and sum the corresponding array values. Any ideas?
% Old Data
descr = {'A','B','C','A','B'}
value = [2,4,6,-5,8]
% New Data
descr = {'A','B','C'}
value = [-3,12,6]

See if this does what you want:
descr = {'A','B','C','A','B'};
value = [2,4,6,-5,8];
[Uv,~,ref] = unique(descr);
acc = accumarray(ref, value');
Result = table(Uv', acc)
Result =
Var1 acc
____ ___
'A' -3
'B' 12
'C' 6
The table output is optional, and just shows the result.
