Uploaded Image: theone.jpg

You are the chosen ONE=NEO! and you must multiply two matrices. Here is what you know:



Name: Matrix A

Dimensions: 3x2 (rowsXcolumns)

What A looks like:

Name: Matrix B

Dimensions: 2x4

What B looks like:

The oracle tells you more about them. They are:

Associative

A(BC) = (AB)C

Distributive

A(B + C) = AB + AC

Compatible with scalars

d(AB) = (dA)B

Armed with this information, you must fulfill your destiny as the One...



You must Multiply them...




But wait! The agents of miscalculation will track you down unless you keep these in mind!


  1. Columns of A must = Rows of B

  2. AB does not necessarily = BA

  3. Just because AB = 0 does not imply A=0 or B=0

  4. And you need to be able to find the dot product of vectors.

(#,#) = (row,column)





The solution is so simple yet easily missed:

To get (Row x, Column y) of AB:

You must dot product Row x of A and Column y of B.


Show off your skills by understanding this other example of matrix multiplication!
