A black screen on your computer can mean several things. A black screen is most commonly a screen saver, but there are other possibilities. My computer switches to a black screen after about 5 to 15 minutes of use. Then I have to turn it off to get another 5 to 15 minutes of use.
Time and frequency domain for the same signal. A fast Fourier transform (FFT) algorithm computes the discrete Fourier transform (DFT) of a sequence, or its inverse. Fourier analysis converts a signal from its original domain (often time or space) to a representation in the frequency domain and vice versa.ime and frequency domain for the same signal.

'XLimMode' is used to determine if MATLAB is controlling the X-limits or if you are controlling them. By default, it is set to 'auto', which implies that MATLAB chooses the limits. To prevent MATLAB from changing the limits when the figure is resized or printed, set this property to 'manual'.
