How to use a for loop to calculate the sum of a row vector?

I have the values x-[1, 23, 43, 72, 87, 56, 98, 33] How do you calculate the sum (which should equal 413) using a for loop?

Answer 1

[Stalin Samuel]

x = [1, 23, 43, 72, 87, 56, 98, 33] ;
y = 0;
for n = 1:length(x)
    y = y + x(n);
end

Thank you so much!

[James Tursa]

Better to use a variable with a name other than 'sum', since that is the name of an existing MATLAB function.

Needed this, thanks for the post!

what is the use of x(n).

[Lucas Glasshart]

Ok, now how do you get it to display the result?

[Yue ZHAN]

what about multiply these elements together?

[Christopher Vargas]

disp(y) %this will display the result

[Lexi Finke]

how do you make this loop into a function??

Write a program (using loops) that calculates and displays the sum of all the elements of x=[2 -5 6 7; -4 8 -5 6];(its a question)

[Yadu Bhusal]

X =['enter an array>']; m = length(x); Sum = 0; For i = 1:m Sum = sum + X(i); end Disp(sum)

IF you want single sum. It you wish iterations remove semicolon from end of X(i).
