Resolving Parse/Undefined Errors
2 views (last 30 days)
The last error I'm getting for a school project. When I run code to adjust the values of an input array, it returns a message stating that 'omega' and 'h' are undefined functions or variables. I haven't run into this before, mostly because MatLab hasn't ever had an issue with parsing or giving a variable type to any of my lines. I'm wondering if it may occur with the for loop, once 'omega' and 'h' are remedied. Does anyone know how to address this?
function y = Filter(u)
c = 343; % m/s
f = 1000; % Hz
omega = 2 * pi * f;
j = sqrt(-1);
h = ifft(sqrt(j * omega / c));
x_s = 0;
for i = 1:length(u)
u(i) = (1 / (2 * pi)) * u(i) * h * (x_0 / (abs(x_0 - x_s)^2));
% we will be implementing the phase delay my adding empty samples on
% the beginning of the sample array
y = u;
All help is most appreciated.

I ran the part of the code from my end and for me omega is not undefined and also h is properly defined. I think issue might be coming from some u value which is coming from some other piece of code.
Attached is the screesnshot of values read properly in the window and working fine.
Hope it helps !
