Vectors in Mathcad

Hello,

I am using vectors in mathcad. For some reason when i divide two vectors it produces a scaler. Any ideas on what I am doing wrong?

Thanks,

Yes, the vectorize operator is the way to go.

The vectorize operator can be found on the matrix toolbar.

Can you post an image of the problem I currently don't have Mathcad?

Are you trying to divide element by element? If so, you could use the vectorize operator.

Hello Mike,

I have attached a picture of the code. And I lied. I'm trying to multiply to vectors together; Vel_D and D_D.

I appreciate your help,

D

I now have Mathcad can you post the worksheet.

Looking at the image it seems that the vectorize operator will work.

Defining vector multiplication (or division) using the standard multiplication sign has always been assumed to be the vector dot product, which results in a scaler answer. (The cross-product is available for three-element vectors.) To multiply element-by-element requires that the product be "vectorized," as you have already found out. It can also be done by indices, but the process is much slower.
