[Kai Torben Ohlhus]

Update of bug #58093 (project octave):

                Severity:              3 - Normal => 2 - Minor              
                Priority:              5 - Normal => 3 - Low                
              Item Group:    Matlab Compatibility => Unexpected Error       
                  Status:                    None => Invalid                
             Open/Closed:                    Open => Closed

Follow-up Comment #2:

If you type in the correct Matlab code in Octave using ".*", both Octave and
Matlab deliver the same result.  You 

The correct code using element-wise operations of the screenshots is:


x = 0:0.1:0.5;
y = 3*(1-x).^2.*exp(-x.^2)


If you want to compute a dot product, following the rules of linear-algebra
and vector multiplication, use either of


x = 0:0.1:0.5;
y1 = 3*(1-x).^2;
y2 = exp(-x.^2);
y = dot (y1, y2)
y = sum (y1 .* y2)
y = y1 * y2'


in Octave or Matlab.
