Algebra X And Y Calculators

Often, measured data is comprised of N sampled values of z, evaluated at N locations (x,y). With this function, you can calculate the coefficients of the best-fit x,y polynomial using a linear least squares approximation.You can use this function if you have a set of N data triplets x,y,z, and...

This script plots two sets of 1D data on the same figure with two separate axis and with the same gridding.The code also checks if the x-axis data are the same, if the x-axis dataare not the same, it draws an additional x-axis on the top of the figure.The two sets of data with their axes are...

calculates surface area A and its standard uncertainty uA for any arbitrary polygon in a plane given by coordinates x and y and their respective standard uncertainties ux and uy. The inputs are assumed to be VECTORS, x, ux, y and uy all should have the same size. The uncertainties are assumed to...

D = DISTMAT(X,Y) for matrices X and Y returns the distance matrix where the (i,j)th entry is the d-norm distance between the ith and jth row of X and Y respectively.DISTMAT(X,Y,d) computes a specific d-norm distance. Default=2[D,XI,YI]=DISTMAT(X,Y,d,var) gives the indices of the sorted values of...

Given a vector of x- and y-coordinates of a data set, allows the user to select a subset of the data with the mouse and change the coordinates of that subset much as he/she moves icons around a desktop. There are three modes of selecting the data - 'lasso-ing' the data much like in MS Paint, a...

This m-file gives the expansion of powers of sums of any real or complex numbers x and y, and any negative integer n. In 1676 Newton showed that the binomial theorem also holds for negative integers n, which is the so-called negative binomial series and converges for |x| < y. From this emerges...

This m-file gives the expansion of powers of sums of any real or complex numbers x and y, and any nonnegative integer n. It is also known as the Newton's binomial. From it emerges the discrete binomial (positive) distribution.Syntax: function bintheor(x,y,n) Input:x,y - pair of interested terms...

The two inputs X and Y are vectors defining a set of N points. The function uses Lagrange's method to find the N-1th order polynomial that passes through all these points, and returns in P the N coefficients defining that polynomial. Then, polyval(P,X) = Y.R returns the x co-ordinates of the N-1...
