Polynomial Interpolation

Ever wonder how the weights and abscissae are calculated for the numerical conversion from radiance to flux? The long and the short of it is that Gauss-Jacobi quadrature determines the weights and abscissae which is similar to Gaussian for low-point quadrature but differs substantially for...

type "untitled" to run.The 7 bit data can be inputted or generated randomly.The crc polynomial used is fixed and cant be changed.The function that calculates and verifies the crc is " mycrc ".The file untitled is the gui but its m file also contains code for generation of random data. Iv included...

While interpolation functions are available builtin in MATLAB, it requires data in specified griddata format. Consider sampling data from an experiment and you are missing some points and you don't want to repeat the experiment but require data at all grid-points for full calculation. This might...

[M, L] = jury(P,N)This function gives the Jury's array from a numerical or SYMBOLIC polynomial and includes the two special cases: (1) the first element of the second row of a block is zero; (b) a row of zeros (when there are roots on unit circle or reciprocal roots like (r,1/r). The symbolic...

Kriging and inverse distance are popular interpolation methods, especially in earth sciences. There are some routines already available on matlab but are severely limited by matlabs memory constraints. By using gstat to handle interpolation and variogram modelling, very large datasets are easily...

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.

Use coeffs = fit2dPolySVD(x, y, z, order) to fit a polynomial of x and y so that it provides a best fit to the data z.Uses SVD which is robust even if the data is degenerate. Will always produce a least-squares best fit to the data even if the data is overspecified or underspecified.x, y, z are...
