Interpolate

SQL::Interpolate is a Perl module to interpolate Perl variables into SQL statements. SYNOPSIS use SQL::Interpolate qw(:all); # Some sample data to interpolate: my $s = blue; my @v = (5, 6); # Variable references are transformed into bind parameters. # The most basic usage involves...

A suite consisting of two functions that interpolate thermodynamical properties of air between 100-2500 K.Lookup tables given as .mat-files.Vectors of temperatures and properties are accepted. Platforms: Matlab

Normal interpolation methods takes equally spaced/user-generated x-data as input and outputs new interpolated y-data with non-uniform spacing.This function generates y-data with equal spacing, and interpolates/generates the x-data (linear interpolation). The spacing can be specified as optional... Platforms: Matlab

Plots the contours of a function defined on an unstructured triangular grid directly, without the need to interpolate back onto a Cartesian array.I have attempted to replicate much of the functionality of the regular "contour" function.Type "help tricontour"Type "contourdemo" for some examplesYou...

FindGraph is a comprehensive graphing, curve fitting, and digitizing tool. FindGraph offers 12 generic fits, including linear regression, logistic functions, fourier approximation, rationals, neural networks, B-splines and parametric curves least squares approximations, plus a library of over 300...

Linear Interpolation Calculator is a free solution that gives you the possibility to interpolate between values to arrive to the correct intermediate result. Linear interpolation has many uses usually in steam tables to find the unknown value. Platforms: Windows

Create large images from small inputting while keep the best quality. A unique algorithm are used to make sure the quality of enlarging is better than traditional pixel interpolate methods. When you look at the enlarged image, you can see the edges are still sharp withour blurring and artifacts.... Platforms: Windows, Windows 8, Windows 7, Windows Server

MATLABs most commonly used 3-d plotting tools surf and mesh require rectangular grids to plot in 3-d, not x,y,z triples. This function converts arrays of x,y,z triples into rectangular grids to use with surf, mesh, etc.common usage:[x y z] = xyzplotter(xin,yin,zin)xin,yin,zin are n x 1 arrays... Platforms: Matlab

This functions uses GRIDDATA to interpolate pixel values from scatterred points on a head image. A reference image can be used to interactively select point locations from the 10/20 international system (EEG electrode position). Options for interpolation include linear and cubic and nearest. The... Platforms: Matlab

Piecewise Hermite cubic interpolation between 2 points knowing derivative valuesSyntax: y=p3hermite(x,pointx,pointy,yprime,plt)Wherepointx = data points of the independent variable (The points do not have to be equally spaced)pointy = data points of the dependent variable. pointy is the value of... Platforms: Matlab

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. Platforms: Matlab

One cannot interpolate a complex number in the form of Real + j*imaginary.The only way to do interpolation is on the complex representation of an amplitude + phase. But sometimes the phase is not continuous, and given in the modulo(2*pi) representation (such as the result from the "FFT"... Platforms: Matlab

This function will return a 29-point equal loudness contour for your desired phon level. The frequencies evaulated in this function only span from 20Hz - 12.5kHz, and only 29 selectivefrequencies are covered. This is the limitation of the ISO standard.In addition the valid phon range should be 0... Platforms: Matlab

EMPRAND generates random numbers from empirical distribution of data. This is useful when you do not know the distribution type (i.e. normal or uniform), but you have the data and you want to generate random numbers form that data.The idea is to first construct cumulative distribution function...

Dataset and m files for the Computational Statistics webinar.myloess.m is used to interpolate a LOESS curve. chole_loess.m is the primary m files used during the webinar. Platforms: Matlab

FILLNANS replaces all NaNs in array using inverse-distance weighting.Y = FILLNANS(X) replaces all NaNs in the vector or array X by inverse-distance weighted interpolation: Y = sum(X/D^3)/sum(1/D^3)where D is the distance (in pixels) from the NaN node to all non-NaN values X. Values farther from a... Platforms: Matlab

I threw this together for myself, because I wanted a version of interp with differences 1, 2, and 3 (below). I'm sure it's not as fast as it could be - feel free to comment on any potential improvements, or on any bugs.Differences from MATLAB built-in functions: 1. MUCH faster 2. Extends border...

This function "refinepatch" can refine any triangular mesh surface ( patch) with 4-split spline interpolation, see screenshot.Literature:The spline interpolation of the face edges is done by the Opposite Edge Method, described in: "Construction of Smooth Curves and Surfaces from Polyhedral... Platforms: Matlab

A common request is to interpolate a set of points at fixed distances along some curve in space (2 or more dimensions.) The user typically has a set of points along a curve, some of which are closely spaced, others not so close, and they wish to create a new set which is uniformly spaced along... Platforms: Matlab

Polarplot3d produces surface and mesh plots for three dimensional polar data. A labeled polar axis is drawn at a fixed height or it can follow the surface contour at maximum radius. A polar grid can also be drawn on top of the surface.This function is based on polar3d by J De Freitas, file... Platforms: Matlab
