Question

Given the following code, determine the amount of memory required to store all of the variables after the program has been executed (Hint: sum the variables) show your work. Then, tabulate your results in the form of the table below (a separate table ffor each part) then add to your report.
Variable datatype    Memory for datatype (bits) # of elements Memory (bits) a logical 8 1 8*1 = 8 . . . . . . . . . . . . . . . sum (bytes)

(a)
clear all clc
a=2; b=[5 1];

c = ~(a > b);

d = uint16(c);

e = [ b b a a];

f=single(a);

(b)
clear all clc
d=[1 2 3; 4 5 6; 7 8 9]; s=0;
[nr,nc]=size(d);

for ir=1:nr

for ic=1:nc

s = s + d(ir,ic);

end

end

m = s/(nr*nc);

(c)

clear all

clc
c = uint8(0);

happy=true;

out=[];
while(happy)

c = c + uint8(1);

out = [out double(c) ];

if(c>4)

happy = false;

end

end
q =10:-2:0;

r = single(q(1:3));

s = rand(3,1);

The amount of memory required to store each variable and the total amount of storage required to store all of the variables after the execution of the program is given below in Tabular Form.

Code a

Variable Name	Datatype	Dimension	Effective number of element	Bytes allocated per element	Total Bytes allocated to the variable
a	double	11	1	8	8
b	double	12	2	8	16
c	logical	12	2	1	2
d	unit16	12	2	2	4
e	double	16	6	8	48
f	single	11	1	4	4
Total					78

Code b)

Variable Name	Datatype	Dimension	Effective number of element	Bytes allocated per element	Total Bytes allocated to the variable
d	double	33	9	8	9*8 = 72
ic	double	11	1	8	8
it	double	11	1	8	8
m	double	11	1	8	8
nc	double	11	1	8	8
nr	double	11	1	8	8
s	double	11	1	8	8
Total			15	8	15*8 = 120

Code c:

Variable Name	Datatype	Dimension	Effective number of element	Bytes allocated per element	Total Bytes allocated to the variable
c	unit8	11	1	1	1
happy	logical	11	1	2	1
out	double	15	5	8	40
q	double	16	6	8	48
r	single	13	3	4	12
s	double	31	3	8	24
Total					126

Refer to the command "help double" to know how many bytes of memory is allocated when we assign a variable of datatype double.
