**How to work out the position vector? MATLAB Answers**

A frequent misuse of inv arises when solving the system of linear equations Ax = b. One way to solve the equation is with x = inv(A)*b . A better way, from the standpoint of both execution time and numerical accuracy, is to use the matrix backslash operator x = A\b .... damp(sys) displays a table of the damping ratio (also called damping factor), natural frequency, and time constant of the poles of the linear model sys. For a discrete-time model, the table also includes the magnitude of each pole. Frequencies are expressed in units of the reciprocal of the

A frequent misuse of inv arises when solving the system of linear equations Ax = b. One way to solve the equation is with x = inv(A)*b . A better way, from the standpoint of both execution time and numerical accuracy, is to use the matrix backslash operator x = A\b .... In general, to return a FFT amplitude equal to the amplitude signal which you input to the FFT, you need to normalize FFTs by the number of sample points you're inputting to the FFT.

I'm actually not sure quite how Matlab decides what exponent to use when printing out. Obviously, if A is close to 1 (e.g. Obviously, if A is close to 1 (e.g. A = [100, 203] ) then it won't use an exponent at all but this solution will return 2.... Some terms: The Fast Fourier Transform is an algorithm optimization of the DFT—Discrete Fourier Transform. The “discrete” part just means that it’s an adaptation of the Fourier Transform, a continuous process for the analog world, to make it suitable for the sampled digital world.

- Now i need to calculate the number of peaks in the graph and work out the BPM

- On the other hand if you do not want/care about a physical meaning, but want to know how the fourier amplitudes of each band vary relative to each other, you can stick to absolute magnitude.
