This week we continued our exploration of Linear Algebra and were introduced to Object Oriented Programing in R. We were given the following code to initialize the matrices A and B and asked to find A+B and A-B

We were then introduced to the diag() function and asked to create a matrix with the following values in the diagonal: 4,1,2,3

Finally, we were asked to recreate a 5×5 Matrix and were given the hint: use diag()

All in all, this week made much more sense than last week’s. This week I was able to visually track how matrix addition and subtraction worked while matrix multiplication might have well have been magic, to quote my Calculus professor. I feel a lot more comfortable with matrices after this week as compared to last week!
