Inverse Functions

A collection of functions for calculating the upslope area and related measurements for a digital elevation model (DEM).Based on the method of Tarboton.See also the upslope area postings on my image processing blog, March-August 2007, http://blogs.mathworks.com/steve.Requires Image Processing...

TYPECAST and TYPECASTX are mex functions intended to mimic the MATLAB intrinsic typecast function with extensions. These C-mex versions of typecast differs from the intrinsic typecast in the following important aspects: Intrinsic typecast------------------Type of copy: Deep Data CopyAllows... Platforms: Matlab

[psi gopt] = dfdesign_w(phi, w, d);DFDESIGN_W computes the H-infinity optimal inverse filter of a given filter phi(z).The resulting filter psi(z) minimizes the H-infinity norm of the error systemE_w(z) = [z^(-d) - psi(z)phi(z)]w(z).If an error occurs, use "dfdesign_w_lmi.m".[INPUT]phi: target...

An implementation of the image normalization (and inverse normalization) part of P. Dong et al.'s paper: "Digital Watermarking Robust to Geometric Distortions," IEEE Trans. Image Processing, Vol. 14, No. 12, pp. 2140-2150, 2005. Platforms: Matlab

[Th, H] = JACOBITHETAETA(U,M) returns the values of the Jacobi's theta and eta elliptic functions TH and H evaluated for corresponding elements of argument U and parameter M. Platforms: Matlab

The MATLAB toolbox offers two particular functions working on vectors as the vector cross product and the dot product. These functions are implemented to work on a general matrix dimension. Unfortunately, this implies a long overhead and slows down the performance significantly.This archive... Platforms: Matlab

This is a simple example of how nested functions can simplify the writing of callback functions for writing continuously-running applications. Callback functions are used by timer objects and the various objects in the Test & Measurement Toolboxes (Data Acquisition Toolbox, Instrument Control... Platforms: Matlab

At the moment, the Normal Inverse Gaussian (NIG) distribution is not included in the statistics toolbox. This collection of m-files supplements this toolbox with the most important functionalities for the NIG distribution: random numbers, moments, cdf, pdf and parameters by moment fit. This...

This toolbox estimates the following volatility loss functions:1. Mean Square Error, MSE2. Mean Absolute Deviation, MAD3. Mean Logarithm of Absolute Errors, MLAE4. Heteroskedasticity-adjusted Mean Square Error, HMSE5. Heteroskedasticity-adjusted Mean Absolute Error, HMAE6. Median Absolute Error,... Platforms: Matlab

The m-file finds the elimination matrices (and scaling matrices) to reduce any A matrix to the identity matrix using the Gauss-Jordan elimination method without pivoting. Using the matrices gotten it computes the inverse of the A matrix. Platforms: Matlab

Functions that checks if a number is odd or even.(This is a little bit more complicated than using "mod(x, 2)" if you want error handling for certain cases.)The function can handle double, single, and integer classes, as well as arrays of these.* An error is raised if a floating point number is...

The Fourier transform takes a signal in the time domain and maps it, without loss of information, into the frequency domain. The frequency domain representation is exactly the same signal, in a different form. The inverse Fourier transform(IDFT) maps the signal back from the frequency domain into... Platforms: Matlab

Wrapper for fprintf-like print functions with automatic indentation capabilities, based on format string processing.The default mechanism automatically indents the output based on the length of the function call stack. The indentation hence directly reflects the depth of the function from which... Platforms: Matlab

You can follow the examples given in the codes, to construct your 2-Dfuction in 2-D Laplace transform domain, insert it into the place of our examples, then you can get the inverse 2-D Laplace transform of your function. Platforms: Matlab
