Exercise $3.($CS $1\mathrm{.}5)$

Consider the following MATLAB code:

$1$ A $=[21/4$ ; $01]$;

$2$ j $=0$;

$3$ B $=$ A ;

$4$ while B $(1,2)<4$

$5$ B $=$ B $*$ A ;

$6$ j $=$ j $+1$;

$7$ end

a$.$ What are the values of B and j before the while loop?

b$.$ What are the values of B and j after one pass through the while loop?

c$.$ What are the values of B and j after two passes through the while loop?

d$.$ How many times do we pass through the while loop until the loop terminates?

e$.$ After the while loop terminates, what are the values of B and j$?$
