Build Matrix to compare Models

[unify123]

Hi, 

I want to build a Matrix for this Sample Data

Model	Type
Model 1	A45
Model 1	A12
Model 2	A45
Model 2	B23
Model 2	A12
Model 3	A45
Model 3	B23
Model 3	E24

From this Data i want to find out the absolute differences and get a Matrix like this.

	Model 1	Model 2	Model 3
Model 1	0	1	2
Model 2	1	0	2
Model 3	2	2	0

Can someone help me and give me an advice how to come to the solution.

Thanks a lot.
