MATLAB: Summation with FOR Loop

for loopsummation

Hello, Super noob question, but how do I do the attached picture in MatLab using a FOR loop. I just need to know how to set up the loop, not the actual values. Thanks for any help!

Best Answer

omega=...;
t=...;
N=...;
summe = 0.0;
for k=1:N
  summe = summe + sin(omega*t*(2*k-1))/(2*k-1);
end

Best wishes

Hi,

Use a nested for-loop for this. Outer loop counts up from i=1 to N and the inner loop from n=1 to N.

for n = 1:N
    for k = 1:N
        r_0 = sum(rho_kn * r_k0 * r_n0);
    end
end
r_0 = sqrt(r_0);

Note:

I replaced "i" by "k" here, because you could get in trouble when using i for loop count in combination with complex numbers. So i isnt recommended to use as a variable in matlab code.

Best regards

MATLAB: Trying to use summation notation in a for loop

Firstly, this code will give an error since X vector is 1x63 and n is 1x5. There will be a size mismatch. You have to correct this. Use the following code.

x = -pi:0.1:pi;
ye = cos (x);
n = length(x);%has to be same size with x
i = 1:n;
for k = 1:n
  summe = summe +((-1).^(i)).*((x.^(2.*i))./(factorial(2.*i)));
end
plot(x,summe)
