MATLAB.[z, p, k] = ztrans(x, n, 's')。Inputs:x: Input discrete-time signal vector.n: Vector of time indices for the input signal.s: Complex variable representing the frequency (in radians per second) at which the z-transform is evaluated.Outputs:z: Vector of z-transform values at the specified frequency.p: Vector of poles of the z-...
Tips If any argument is an array, thenztransacts element-wise on all elements of the array. If the first argument contains a symbolic function, then the second argument must be a scalar. To compute the inverse Z-transform, useiztrans. ...
This intuitive introduction shows the mathematics behind the Z-transform and compares it to its similar cousin, the discrete-time Fourier transform. Mathematically, the Z-transform is straightforward—it’s just a bunch of multiplications and additions, and you’ll learn how to solve an equation fo...
This MATLAB function returns the length-m chirp Z-transform (CZT) of x along the spiral contour on the z-plane defined by w and a through z = a*w.^-(0:m-1).
i am currently working on applying z transform for images. in matlab, there is a function called ztrans in symbolic math toolbox for applying z transformation for symbolic expressions or matrix of symbolic expressions. could any one please suggest me how to apply z transformation for images, jus...
