Question

In each of the below syntax exercises, determine the output that results from running the specified MATLAB program.  If there is no output because an error results, write “ERROR” and then explain why the error occurs.

clear; clc

a = 3;

b = 2;

c = 1;

for m = 1:3

for n = 1:3

if n < m

     a = b - c

elseif n == m

b = a + 1;

else

c = 2*b + a;

end

end

end

a

b

c

Answer 1

Output from the results of running specified matlab program is :

a = -7
a =  13
a =  13
a =  13
b =  14
c = -19

In outer loop m takes values 1 ,2 ,3 and in inner for loop n takes values from 1 , 2, 3

m = 1 , 2 , 3

n = 1 , 2 , 3

value of a is displayed when n<m which occurs three times for following combinations of n,m

{n,m} = {1,2} , { 1 , 3 } , { 2, 3 }

For these three case we arrive at first three answers of solutions which are

a = -7

a = 13

a = 13

and last three parts are diplayed as a result of end computation of results which are

a = 13

b = 14

c = -19
