Hermite main interpolation functions for two dimensional surface (update 24 07 07) in matlab

The following Matlab project contains the source code and Matlab examples used for hermite main interpolation functions for two dimensional surface (update 24 07 07). DESCRIPTION: Under the bending or twisting effect a thin-plate element's conforming shape functions be derivative basis displacement functions on Pascal Triangle.

B spline tools in matlab

The following Matlab project contains the source code and Matlab examples used for b spline tools. B-splines is a natural signal representation for continous signals, where many continous-domain operations can be carried out exactly once the B-spline approximation has been done.

Performs sinc interpolation, and also resampling of a intput waveform in matlab

The following Matlab project contains the source code and Matlab examples used for performs sinc interpolation, and also resampling of a intput waveform . %Interpolating and resampling function, where: % I = interpolation rate % D = resampling location, number of samples to shift % x(n) = input waveform % y(n*(1/I) + D) = output waveform % --includes option smoothing with an exponential % decaying function to reduce Gibbs ringing.

Multidimensional interpolation with integer inputs in matlab

The following Matlab project contains the source code and Matlab examples used for multidimensional interpolation with integer inputs. iminterpn uses Image Processing Toolbox functions to implement multidimensional interpolation. Unlike the MATLAB function interpn, iminterpn can interpolate an integer array (such as uint8, uint16, etc.) without converting it to double.

Biparabolic interpolation in matlab

The following Matlab project contains the source code and Matlab examples used for biparabolic interpolation. Code to interpolate surface values using a parabolic approximation in both X and Y directions. Parabola coefficients are further used to calculate approximated values of first and second partial derivatives at the requested node of interpolation.

2d cubic beizer curve in matlab

The following Matlab project contains the source code and Matlab examples used for 2d cubic beizer curve. "Funct_Bezier.m" a function to evaluate and plot 2D cubic bezier curve for given four control points and interval. Utilizes Horner's rule for efficient compuation. A simple test program is given "TestCubicBezier.m"

Analysis of river bathymetry data using different interpolation methods from matlab's 'griddata'.

The following Matlab project contains the source code and Matlab examples used for analysis of river bathymetry data using different interpolation methods from matlab's 'griddata'. . This function carries out the following tasks: 1) Imports a set of xyz scatter data, interpolates them to a uniform mesh, where the user defines the interpolation method and mesh resolution.

My bezier in matlab

The following Matlab project contains the source code and Matlab examples used for my bezier. This is a routine used for constructing Bezier Curves for a given set of control points. It also constructs the sub-divided Bezier Curve specified by the given limits of parameter values, along with the control points for the same.
