This demo shows how you can create a COM component from a MATLAB code using MATLAB COM Builder and use the same in an external project independent of MATLAB. This demo compiles a function that uses MATLAB Interpolation capability into a COM component and uses it in an external Visual Basic... Platforms: Matlab

The linear Stochastic Differential Equation (LSDE) is very widely used equation in the noise analysis of LTI circuits. It involves the input signal to be perturbed with Gaussian white noise. To find the solution statistics like mean, varaiance is a tasking job and requires full power of... Platforms: Matlab

This programme is about finding many examples of Ramanujam's Diophantine Equation. For mathematical formulas used in making this programme, I have referred to the article MATHEMATICAL MINIATURE 9.pdf by John Butcher, butcher@math.auckland.ac.nz.To circumvent the problem of editing the Greek...

Syntax: ui=NewtFit(x,y,z,u,xi,yi,zi)3D interpolation. It may be used where griddata3 fails to find a triangularization of the datagrid (x,y,z). The function uses a modified 4 point Newton interpolation formula for vector arguments in 3D instread of scalars used in 1D. The interpolation is... Platforms: Matlab

This is a solution of Hermite interpolation problem. example: A=[-1 2 -1 inf; 0 1 inf inf;1 -1 -1 8] x f(x) f'(x) f''(x) . . . A = -1 2 -1 Inf 0 1 Inf Inf 1 -1 -1 8 If you don't know the derive values, just write Inf. Use this command: difftable(A) And you can see the divided difference table,... 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

This function performs interpolation faster than MATLAB's "interp1" function. In the limit of small library and search arrays, it is ~5x faster. In the limit of large library arrays, qinterp1 has a flat scaling, while interp1 has a linearly increasing scaling (see the image for this file).... Platforms: Matlab

When interpolating a multivalued function (more than one y for each x), interp1 produces, at best, an error (if there are identical x data), and at worst, garbage (see the attached image). This function performs meaningful interpolation of a multivalued function, when the inverse (x = g(y)) is a... Platforms: Matlab
