Interpolation

The program does interpolation or decimation on a given 1-d data in an array.Given X with sampling rate Ft Hz and is used to generate another sequence Y with sampling rate Ft' Hz, then Sampling Rate ratio R is given by, Ft' R = ---- Ft if R > 1, sampling process is known as interpolationR < 1,...

This MEX performs 2d bilinear interpolation using an NVIDIA graphics chipset. To compile and run this software, one needs the NVIDIA CUDA Toolkit (http://www.nvidia.com/object/cuda_get.html) and, of course, an NVIDIA graphics card of reasonably modern vintage.BUILDING INSTRUCTIONS: Change the...

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...

The INTERPFT function does sinc interpolation by taking an FFT, padding its end with zeros, and then taking an IFFT. Essentially, INTERPFT resamples the signal after low-pass filtering it.Instead of putting all zero padding at the FFT *ends*, that padding can be split so that some are at the...

Sometimes it is important to be able to estimate the peak of a sampled continuous function between the samples. This is called subsample peak interpolation and is used in radar, delay estimation, and communication. Typically one fits a model to the sampled data and then finds the maximum of the...
