Adding number within a range

Q - Write a piece of code that will sum all the numbers between 1 and abcd.

a = 8 b = 8 c = 3 d =1

New to MatLab and am struggling with this one, hope you can help!

Thanks

For homework help, please post what you have tried, and ask specific questions about where you are stuck. That way we can help in ways that are not simply doing your homework for you.

If you have literally no idea on how to start, I would recommend going to your instructor.

between 1 and 8831?

[Joshua Jones]

for ii = 1:(a*b*c*d)

my_sum = my_sum + ii

end

my_sum = 18528

is this correct?

[Ameer Hamza]

Joshua, I guess the actual question regards abcd as consecutive digits rather than a*b*c*d. So you have to find a way to make

a = 8;
b = 8;
c = 3;
d = 1;

into 8831.

Joshua Jones , based on your previous comment, you want to sum all values from 1 to (8*8*3*1), or, from 1:192. Is that correct?

If so, no loop needed.

my_sum = sum(1:a*b*c*d)

[Joshua Jones]

Hi, yeah that works perfectly!

Thank you

no loop needed.

my_sum = sum(1:a*b*c*d)
