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.
Symmetry: When the region between 0 and fs is examined, it can be seen that there is even symmetry around the center point, 0.5fs. 4. Matlab and the FFT Matlab's FFT function is an effective tool for computing the discrete Fourier transform of a signal.The following code examples will help you to understand the details of using the FFT function.ymmetry: When the region between 0 and fs is examined, it can be seen that there is even symmetry around the center point, 0.5fs. 4.

The name of the function-that is, how to call it in MATLAB-is determined by the name of the file containing the function. This method is good for functions of any complexity, since the file can contain a multitude of expressions, create local variables, and return as many variables as specified in the file.
