Fft vs Fourier Transform Matlab/python 1

[jakordas]

I am taking a structural dynamics course and I have been asked for a small assignment to graph a function, graph the Fourier Transform, then graph the inverse Fourier Transform. I have heard that the FFT and IFFT is not as accurate as using the Fourier Transform. I just want to know if that is true and what other limits the FFT and IFFT have? Thank you.

I don't think that your statement is right or realistic.
FFT is the method to calculate fourier transform. it is an algorithm to speed up and reduce traditional calc.
not a new concept of the transform itself.

I didn't think this was accurate, that's why I was asking about. I'm new to the concept of the Fourier Transform and MATLAB.
