Barnes interpolation

Barnes interpolation, named after Stanley L. Barnes, is the interpolation of unevenly spread data points from a set of measurements of an unknown function in two dimensions into an analytic function of two variables. An example of a situation where the Barnes scheme is important is in weather forecasting where measurements are made wherever monitoring stations may be located, the positions of which are constrained by topography. Such interpolation is essential in data visualisation, e.g. in the construction of contour plots or other representations of analytic surfaces. (Wikipedia).

Programming Terms: String Interpolation

In this programming terms video, we will be going over string interpolation. String interpolation is the process of evaluating a string containing one or more placeholders and yielding a result in which the placeholders are replaced with their corresponding values. Let's take a look at thi

The Vandermonde Matrix and Polynomial Interpolation

The Vandermonde matrix is a used in the calculation of interpolating polynomials but is more often encountered in the proof that such polynomial interpolates exist. It is also often encountered in the study of determinants since it has a really nice determinant formula. Chapters 0:00 - In

Maryna Viazovska (EPFL): Fourier interpolation

This lecture is about Fourier uniqueness and Fourier interpolation pairs. Suppose that we have two subsets X and Y of the Euclidean space. Can we reconstruct a function f from its restriction to the set X and the restriction of its Fourier transform to the set Y? We are interested in the p

stringr: String Interpolation

The stringr library is part of the R tidyverse and provides a range of convenience functions for working with character strings. In this lesson, we learn how to use stringr to string interpolation: filling values into a string based on stored variables, calculations, function calls and dat

Transpose of matrices

In this very easy and short tutorial I explain the concept of the transpose of matrices, where we exchange rows for columns. The matrices have some properties that you should be aware of. These include how to the the transpose of the product of matrices and in the transpose of the invers

Repulsive Shape Optimization

In visual computing, point locations are often optimized using a "repulsive" energy, to obtain a nice uniform distribution for tasks ranging from image stippling to mesh generation to fluid simulation. But how do you perform this same kind of repulsive optimization on curves and surfaces?
