Hi Tommy,

that's not the problem. To write a = {r1,c1}. Is it possible to write a
general matrix inversion routine for a general matrix with real or complex
elements?  How about a vector (in Eu a sequence) with real or complex
elements, the data types of which you dont know in advance? 

Could you write:

a = sqrt(-23.0)  -- you could use a specialy written function
b = sin(3.0)     -- you supply olso your special function
c = a*b          -- this should NOT be a function!

Of course you can circumvent the special case, but only these special
cases.

Thanks, Rolf
