Zeros

This e-book is based on the Student Edition of MATLAB 7, which includes a symbolic toolbox. The Professional Edition may of course also be used. The goal is to exploit a restricted subset of MATLAB commands and functions to explore most of the elements of undergraduate mathematics. All items from...

zeroPadding2N makes zero padding of a given array to a 2^N length.X_ = zeroPadding2N(X), for array X, returns the array with the necessary appended zeros so it reaches the next power of 2 length.X_ = zeroPadding2N(X, N), for array X, returns the array with the necessary appended zeros so it...

Catoki present a new alternative to MATLAB IDENT GUI. This is friendly interface for system identification SISO. CaToKi is based in a regular course of Identification based in Ljun Book. You can obtain models of easy way: ARX, ARMAX, Outpur-Error and Box Jenkis. Plot your input-output dates....

When doing traditional bode diagram control system analysis of ill-conditioned high order SISO systems in V4.2 with Control System Toolbox, I found using these utilities improved the robustness of my results. There's also a nice function to plot an approximate (asymptotic) bode diagram which I...

This very simple function computes the n n-th roots of a given complex number. The attained complex roots can be plotted on a polar diagram.It is more performante thenroots([1, zeros(1,n-1), -x]),since it is based on very simple geometric properties of complex roots.

shufflelabel randomly changes the order of label values in a label matrix. Zeros and nans are ignored. The label matrix can be every numerical data type, char or a cell array of strings. Example L = kron([1 2 3;3 2 3],[1 1; 2 2]) L = 1 1 2 2 3 3 2 2 4 4 6 6 3 3 2 2 3 3 6 6 4 4 6 6 Ls =...

This function uses vectorised methods to determine the locations of maxima and minima where they exist within a piecewise spline fit. The matlab built-in functions for determining the maxima and minima, by differentiating the pp spline and finding its zeros (using the Spline toolbox), are quite...

Partial sums of Fourier terms for a function with jumps in value or derivative converge poorly, because of the Gibbs phenomenon. This file uses the Fourier coefficients, and locations of the singularities, to construct a different approximation that converges spectrally. For details, see T. A....

Generates a sample of observations having user defined correlation matrix R. Optionally, the user may also define the means and variances. If unspecified, these two arguments will default to a mean vector of zeros and variance vector of ones.

Embiggen is a class that makes Matrix-vector operations easier by virtually matching the size of a vector b to the size of amatrix A. This allows for such code as: C = A + Embiggen(b) Here A is a matrix (for example of size 100x50)b is a vector (for example of size 100x1) And the equation is...

My first Matlab coding attempt so go easy if you find a bug or something. I made this to look at the spacing between eigenvalues of random Hermitian matrices and see how they resemble the spacings of Riemann Zeta function zeros.

This filter could be extended into a 2D image smoothing filter. The kernel can be switched easily.This is a program to test how a gaussian filter works on a set of 1-D data ae.g. a=[1 10 1 10 1 10 1] --- use this as input or use your own 1D dataThis example uses a gaussian filter extracted from...

This program allows users to specify the number of zero layers to wrap around a 3D image matrix.Zero padding allows image processing to occur at the edges of the 3D image. Many image processing filters take into account the values stored in a neighborhood of voxels being evaluated. Therefore, if...

Function that places a 2D matrix B into a larger 2D matrix A. The upper-left corner of B is placed at coordinates (r,c) in A. If (r,c) are not given, then B is put in the upper-left corner of A, a default of (1,1). Some error checking is done first to make sure that A and B are 2D matrices, A is...
