Create a $4$x$3$ matrix M where each entry M$($i$,$j$)$ is i$*$j$.$

a$.$ Compute the transpose of M and assign it to a

matrix called N$.$ What are the dimensions of N$?$

b$.$ Compute M$(3,$:$)$

c$.$ Compute N$($:$,3)$

d$.$ Compute M$([14],[23])$

e$.$ Multiply M by the vector $[415]\text{'}$ and assign

the result to y$.$ What is the size of y$?$
