Elementwise Multiplication and Addition of matrices fails

[imke.krueger]

The following equations fail:

A =3* {{b1 ^{2,b1 * b2,b1 * b3},{b1 * b2,b2} 2,b2 * b3},{b1 * b3,b2* b3,b3 ^2}};

B={{b1 ^{2,b1 * b2,b1 * b3},{b1 * b2,b2} 2,b2 * b3},{b1 * b3,b2* b3,b3 ^2}}
+{{b1 2,b1 * b2,b1 * b3},{b1 * b2,b2 ^{2,b2 * b3},{b1 * b3,b2* b3,b3} 2}};

If I change it into

S = {{b1 ^{2,b1 * b2,b1 * b3},{b1 * b2,b2} 2,b2 * b3},{b1 * b3,b2* b3,b3 ^2}};

A=3*S;

B=S+S;

it works.

I am currently working with the nightly build for windows from March 2009.

edit: the same applies for the der()-operator.

Closing this as it seems the code runs in the current trunk. If it does not, reopen the bug and provide a complete model that does not work since equations are not always enough.
