konfo - conformal linear transformation
The matrix A (3x2) contains in the 1st column the z-values and in the 2nd column the w-values, on which the z values are transformed. On the complex values of x this tranformation is used
When you want to realize an inversion, then a is build up e.g. by a=[1,1;1+%i,(1-%i)/2;1-%i,(1+%i)/2]
a=[1,1;1+%i,(1-%i)/2;1-%i,(1+%i)/2]; x=(-10:0.1:10) + %i; y=konfo(x,a);
