Well, first improvement would be to comment your code,
especially if you want other people to read it :-)

Apart from this, here are a few things:
You create a matrix called Tensor but you barely use it as a matrix;
sometimes you use elements of it, e.g. Tensor(1,1),
sometimes you use the values with their original name, e.g. Sigmaxx.
This has probably no influence considering the memory needed and 
calculation time
but some consistency would not hurt.

When you compute several times the same value, you should create a 
variable for it, e.g.

cdS = cosd(Schnittwinkel)

sdS = sind(Schnittwinkel)

TKomponenten= Schnittspannungsvektor*[cdS ; sdS]

TKoordinatenkomponenten=[cdS, sdS ; -sdS, cdS]*TKomponenten

Foo = 2*Tauxy/(Sigmaxx - Sigmayy)

aFoo = 0.5*atand(foo)

bFoo = 0.5*atand(-foo)

Richtungen1 = [0, 90, 180] + aFoo*[1, 1, 1]

Richtungen2 = [0, 90, 180] + bFoo*[1, 1, 1]

Hope this helps
