Help with MATLAB Code - Plot is ignoring 0 value
显示 更早的评论
Hello, I am using R2016b to plot magnitude and phase of a fourier series (periodic), but the plot is ignoring the 0 value of the function. Can anyone tell me if I am missing something in the code? The 0 value is not undefined.

Actually the zero value is undefined, because of a division by zero. You can use isnan to replace this with 0.

Thank you very much. Rik, you are absolutely correct that a is undefined at 0 due to a division by 0. I changed the function using l'hospital's rule to solve for the 0 value.

You should put your code here as text (and use the {}Code button to have a correct markup). That way people can copy and paste your code.
