Hi
I am struggling to display complex numbers in my evaluation version of origin 9. I have the numeric and complex(16) properties enabled.
Thanks |

Since 8.6, in Set Column Values dialog (right click a column and choose Set Column Values... context menu), there are some Common Complex functions to use. They are under F(X): Complex: menu.
E.g.
Imabs( )
Imaginary( )
Imargument( )
Imconjugate( )
Imcos( )
etc.
Thanks, Snow Li

While you can display complex numbers in a column, there is not much you can do with these numbers other than some simple math.
Here is the template for entering complex values:
<sign><real part><sign><imaginary part>i
So if you have three columns of complex with column A of
1.2345+5.6789i
and column B of
8.7654-5.6789i
and you set col(c) = col(a) + col(b)
then you get 9.9999 in c because the imaginary cancels out.
