Matlab code required AArray 1 has 20 values B Array 2 has 21

Matlab code required

[A]Array 1 has 20 values
[B] Array 2 has 21 values

I need to element by element do the following:

A (1) - B (1)

A (2) - B (2)

And somehow be able to discount the last B value

So my last calc will be
A (20) - B (20)

Using
A for loop with storing values and a counter

Solution

Here is the code:

Remeber in matlab Arrays are two dimentioal, Vectors are single dimensional

% Here A with 20 values

A = [11 20 32 4 5 6 7 8 9 10 12 45 8 7 4 6 3 1 2 21];

% B with 21 values
B = [11 20 32 4 5 6 7 7 9 10 12 45 8 7 4 6 3 1 2 20 12];

% A counter variable for arrays

count=1

% for loop for 21 times
for i=1:21

% checking if it is 21 th iteration
if i==21

% if true then breakig the loop
break

% else calculating the value A(count)-B(count) then incrementing the counter variable
else
A(count)-B(count)
count=count+1;

% End of if
end

% End of for loop
end

Ouput:

count =1

ans = 0

ans = 0

....

...

...

ans = 1
