$2)$ Assign A$1$ to $[-2$:$1$:$1$:$-1$:$-2-2$:$2$:$41,$ v$1$ to linspace$(-2,4,4),$ and x to $-2,$ and set A$2$ equal to a $3$X$3$ matrix of all $5\text{'}$s$.$ Compute the following variables first by hand $($don$\text{'}$t turn In$),$ then confirm your result by computing in the script below. If any result is not defined by an operation, Indicate by setting the resulting variable to 'errore.g$.,$ for z$-$ y$\text{'}$A$3,$ write z 'error' if not defined.

a$)$ Using matrix multiplication, multiply A$1$ by A$1,$ set to a

b$)$ Using matrix multiplication, multiply A$1$ transpose by A$1$ itself, set to b

c$)$ Using matrix multiplication, multiply v$1$ by A$1,$ set to c

d$)$ Using matrix multiplication, multiply v$1$ by A$1$ transpose, set to d

e$)$ Using matrix multiplication, multiply v$1$ transpose by A$1,$ set to e

f$)$ Using matrix multiplication, multiply A$2$ by A$1,$ set to f

g$)$ Using matrix multiplication, multiply A$2$ by A$1$ transpose, set to g

h$)$ Using matrix multiplication, multiply v$1$ transpose by vi eself, set to h

$1)$ Using matrix multiplication, multiply v$1$ by v$1$ Iranpose, then add x to this result. Set final result to variable, resul

j$)$ First, let A$3-2$'ones$(3,4)$ Next, multiply $2$ by A$1,$ then subtract A$3$ from the result, set the final result to

k$)$ Using matrix multiplication, multiply $|($from the previous problem$)$ by v$1$ transpose, and set the result to k

$3)$ Consider the series Use vectors to compute the sum appropriate $100,$ and sel the result equal to the variable sum$100.$ In this case, array operators may be useful, as opposed to matrix operators. Do not use any loops, but you may use a built$-$in function $($one discussed in class$),$ where
