Matrix multiplication practical example

Let's talk about a practical example of matrix multiplication so that we can tie our theoretical work into a workable example. Two separate electronic vendors are vying for your business to make widgets for your company.

In this example, we can use matrix multiplication to find out which vendor creates a less expensive widget. The parts list that each vendor gave you is as follows:

• Vendor A:Resistors: 5 Transistors: 10 Capacitors: 2

• Vendor B: Resistors: 8 Transistors: 6 Capacitors: 3

You know from the component's supplier catalog ...
