2.11.10  Barycenter of complex numbers : barycentre

See also : ?? and ??.
barycentre takes as argument two lists of the same size (resp. a matrix with two columns):

barycentre returns the barycenter point of the points Aj weighted by the real coefficients αj. If ∑αj = 0, barycentre returns an error.
Warning To have a complex number in the output, the input must be :
affixe(barycentre(...,...)) because barycentre(...,...) returns a point, not a complex number.
Input :

affixe(barycentre([1+i,1-i],[1,1]))

Or :

affixe(barycentre([[1+i,1],[1-i,1]]))

Output :

i
