Question

For each of the below codes, determine if the following MATLAB codes produces an error.

• If the code does NOT produce an error, predict the output.
• If the code DOES produce an error: (1) state what line the FIRST error is found and (2) what the error is

clear;clc
%ICE08B-1
A = [1,5,2,9,4,9];
B(1,5) = 0;
counter = 1;
for i = 1:length(A)
    B(i) = A(i) * counter;
    B(i) = B(i)-2;
    counter = counter + 1;
end

Answer 1

Below is the solution:

The above code does not give the error and simply executed with modified value using the array A value.

for i = 1:length(A)

The for loop runs the array A length times that is A array length is 6

for the very first time in loop

B(i) = A(i) * counter; %i value B(i) is 1*1 = 1
B(i) = B(i)-2; %i value B(i) is 1-2 = -1
counter = counter + 1; %increment the counter

second time in loop

B(i) = A(i) * counter; %i value B(i) = 10
B(i) = B(i)-2; %i value B(i) = 8
counter = counter + 1; %increment the counter

third time in loop

B(i) = A(i) * counter; %i value B(i) = 6
B(i) = B(i)-2; %i value B(i) = 4
counter = counter + 1; %increment the counter

fourth time in loop

B(i) = A(i) * counter; %i value B(i) = 36
B(i) = B(i)-2; %i value B(i) = 34
counter = counter + 1; %increment the counter

fifth time in loop

B(i) = A(i) * counter; %i value B(i) = 20
B(i) = B(i)-2; %i value B(i) = 18
counter = counter + 1; %increment the counter

sixth time in loop

B(i) = A(i) * counter; %i value B(i) = 54
B(i) = B(i)-2; %i value B(i) = 52
counter = counter + 1; %increment the counter

The final B array value is :

-1
8
4
34
18
52

That is output of the B array
