# Set default product

I want to set a default product in Mathematica in place of the standard product. Specifically, I want to change the standard product for CenterDot so that when I perform A.B, where A and B are two matrices, the multiplication of the terms is done using the CenterDot.

Alternatively, is there a way to perform specifying which product I want to use when performing the A.B operation?

• Could you please provide a more detailed example? If your question is too general, it is highly possible that you will not get answers. – Αλέξανδρος Ζεγγ Jun 7 '19 at 7:59

I found a very simple solution. To use the function Inner with the functions Plus and CenterDot. Thanks everyone.
• @ΑλέξανδροςΖεγγ However, I have a question, hope you can help me. I am trying to implement this in something that looks like Sum[A^i, {i, 0, l}]. Where A is a matrix. However, I want that "power" to be the A.A.A....A i times, using CenterDot to multiply the terms. – Alonso Perez Lona Jun 7 '19 at 8:06
