function ind = sortind(varargin) % DESCRIPTION ind = sortind(x,[],dim)%  As sort but keeps only index.%  Calculates the index along dimension of the third argument,%  otherwise along the first non-singleton dimension.% INPUT%  x --     any matrix%  dim --   An integer > 0  indicating the dimension along which the operation will %           be performed. Inputs are the same as to sort.% OUTPUT%  ind --   Index along the dimension of the operation to the sort value.% TRY %  sortind([2.3; 3.2]), sortind(rand(1,2,3),[],2)% SEE ALSO %  sort, max, min, minind% by Magnus Almgren 970525[dum, ind] = sort(varargin{:});
