Formatting Text - MATLAB Simulink
Precision. The precision field in a formatting operator is a nonnegative integer that immediately follows a period. For example, in the operator %7.3f, the precision is 3.For the %g operator, the precision indicates the number of significant digits to display. For the %f, %e, and %E operators, the precision indicates how many digits to display to the right of

Fast Fourier transform - MATLAB fft
To find the amplitudes of the three frequency peaks, convert the fft spectrum in Y to the single-sided amplitude spectrum. Because the fft function includes a scaling factor L between the original and the transformed signals, rescale Y by dividing by L.Take the complex magnitude of the fft spectrum. The two-sided amplitude spectrum P2, where the

Transfer function model - MATLAB
Transfer functions are a frequency-domain representation of linear time-invariant systems. For instance, consider a continuous-time SISO dynamic system represented by the transfer function sys(s) = N(s)/D(s), where s = jw and N(s) and D(s) are called the numerator and denominator polynomials, respectively. The tf model object can represent SISO or MIMO

Reduced row echelon form (Gauss-Jordan elimination) - MATLAB rref
Partial pivoting is the practice of selecting the column element with largest absolute value in the pivot column, and then interchanging the rows of the matrix so that this element is in the pivot position (the leftmost nonzero element in the row).. For example, in the matrix below the algorithm starts by identifying the largest value in the first column (the value in the

Bode plot of frequency response, or magnitude and phase data - MATLAB
bode(sys) creates a Bode plot of the frequency response of a dynamic system model sys.The plot displays the magnitude (in dB) and phase (in degrees) of the system response as a function of frequency. bode automatically determines frequencies to plot based on system dynamics.. If sys is a multi-input, multi-output (MIMO) model, then bode produces
