Hi,
I understand you're facing an error while using the function 'interp1'.
The three parameters used in the 'interp1' function are 'x', 'v', and 'xq'. Among these, 'v' can be a complex number, but 'x' and 'xq' must be real.
Refer to the below documentation for more information:
I assume you are encountering this error after the value of k reaches 1329, because at this iteration, one of the parameters is changing from real to complex.
To check which variable is becoming complex, you can use the 'isreal' function.
Refer the below documentation for better understanding:
Hope it helps!
