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 …

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 …

[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 …

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, …

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 …

[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 …

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