How do I find the two smallest values in varargin?

Question

0 个投票

For example, the varargin input is 5,3,6

I want to multiply the the two lowest values, 5*3.

I have tried this:

      y=sort (varargin,1, 'ascend');
      z=y(:, 1:2);
      area= z{1}*z{2};

This is the error I receive:

Error using sort
DIM and MODE arguments not supported for cell arrays.

function out = two_lowest_values(varargin)
     a = sort(cell2mat(varargin));
     out = a(1)*a(2);

I have also tried this:

      Xs = sort(varargin);
      min2nd = Xs{1,2};
      minVal=min(varargin);
      area=min2nd*minVal;

Error message:

Error using sort
Input argument must be a cell array of strings.
