Calculate the distance between two points as the norm of the difference between the vector elements. Create two vectors representing the (x,y) coordinates for two points on the Euclidean plane.

This MATLAB function computes the discrete Fourier transform (DFT) of X using a fast Fourier transform (FFT) algorithm.

Calculate the 2-norm of a vector corresponding to the point (2,2,2) in 3-D space. The 2-norm is equal to the Euclidean length of the vector, 1 2.

This MATLAB function returns the phase angle in the interval [-π,π] for each element of a complex array z.

Real and imaginary components, phase anglesIn MATLAB ®, i and j represent the basic imaginary unit. You can use them to create complex numbers such as 2i+5. You can also determine the real and …

[V,D,W] = eig(A) also returns full matrix W whose columns are the corresponding left eigenvectors, so that W'*A = D*W'. The eigenvalue problem is to determine the solution to the equation Av = λv, …

If A is a vector, then max(A) returns the maximum of A. If A is a matrix, then max(A) is a row vector containing the maximum value of each column of A. If A is a multidimensional array, then max(A) …

Vector and Matrix Data Normalize data in a vector and matrix by computing the z -score. Create a vector v and compute the z -score, normalizing the data to have mean 0 and standard deviation 1.

[h,w] = freqz(b,a,n) returns the frequency response of the specified digital filter. Specify a digital filter with numerator coefficients b and denominator coefficients a. The function returns the n -point …

The comm.EVM System object measures the root mean squared (RMS) EVM, maximum EVM, and percentile EVM of a received signal.
