Hi Jarek

I am using VectorExpressionEvaluator to do dotproduct of two input vectors. i thought vector inputs are actually vectors and to do dotproduct i need a for loop. But a for loop doesn't work this way. I don't know how to work with bioera vectors.

Look for info about VectorExpressionEvaluator in this section of the manual:

You operate on vector fields, not vectors directly.

what do you mean by this "You operate on vector fields, not vectors directly"?
I want to write a loop that for i=0 to 1024 multiplies value of index i of the vector1 in value of index i of the vector2.
the input and output of VectorExpressionEvaluator don't seem to be really a vector.

If you want to just multiply element wise, then this expression should work:

In1 * In2
