generates zeros of a Hermite polynomial of degree n to tolerance "tol" and their associated weights. Uses recursion relation to generate the Hermite function and finds zeros via change of sign and linear interpolation. If a tolerance is specified, the routine will call itself recursively with a finer grid until convergence is reached, or a maximum number of loops are performed (default 5).
This function allow you to perform 2d interpolation for matlab code that have to be compiled to C.
DDA algorithm uses fast interpolation and rounding method to implement rasterization of lines, triangle and polygons. This technique has been used here to produce a straight line.
This is an image contrast enhancement algorithm that overcomes limitations in standard histogram equalization (HE). The two primary features is adaptive HE (AHE), which divides the images into regions and performs local HE, and the contrast...
The INTERPFT function does sinc interpolation by taking an FFT, padding its end with zeros, and then taking an IFFT. Essentially, INTERPFT resamples the signal after low-pass filtering it.
Instead of putting all zero padding at the FFT...
Colormap is based on the colors used by W. F. Haxby's Gravity field of World's oceans, 1985, developed for geoid and gravity maps. The version used here is formed from a linear interpolation of the GMT color table used by MB-System by David W....
Piecewise cubic spline interpolation and approximated calculation of first and second derivative at the interpolation point.
Using Nearest Neighbor-, Linear-, or Bicubic- Interpolation
Function call: env_secant(x_data, y_data, view, side) Calculates an envelope of data over . Method used: 'secant-method' env_secant() observates the max. slope of every about <view /> points from last junction point, and...

All class is interactive_curve.m file. See help about this class: 1) set current directory to directory where interactive_curve.m place 2) type
cara menentukan interpolasi linier dengan matlab how to determine the linear interpolation with matlab
prg is a semi-automated outlining program on an image. This program enable the user to manually select points on the image to form an outline. The user left click on the image once to make the image active and then left clicks on the region...
When drawing financial time series from various markets, one usually needs to make some adjustments before evaluating the series. One of the major concerns is that due to different national holidays or working days across countries, the dates...
PNGwriter is a very easy to use open source graphics library that uses PNG as its output format. The interface has been designed to be as simple and intuitive as possible.
It supports plotting and reading in the RGB (red, green, blue),...
Content-based image retrieval is the task of searching images in databases by analyzing the image contents. In this demo, a simple image retrieval method is presented, based on the color distribution of the images. The user simply provides an...
Reconstruct an image from parallel projection data using the convolution-backprojection algorithm function [img,H] = CTrecon(prj,varargin)
for a discussion of this function including examples see:...
This is an embarrassingly simple function to augment the currently available MATLAB colormaps. It works as a seamless replacement for the current maps like jet and hsv. So to use it you just call colormap(othercolor('colorname')). The function...
Rigid body 2-D image co-registration (translation and rotation) is performed using maximization of mutual information.
Function is implemented in c-code and compiled using the Matlab compiler to minimize computation time. Current...
Demonstrates the use of thin plate splines based warping for temporal interpolation.
