Piecewise cubic spline interpolation and approximated calculation of first and second derivative at the interpolation point.
ScaleTime - fast linear matrix interpolation
I have recorded timeseries of e.g. size [100'000 x 10] and cut out chunks of about 100 frames according to some events and normalize them to exactly 100 frames.
For this task, the direct...
This function "refinepatch" can refine any triangular mesh surface ( patch) with 4-split spline interpolation, see screenshot.
The spline interpolation of the face edges is done by the Opposite Edge Method,...
IIR Increases the resolution of an image by interpolation
B= IIR(inputfile,f) returns the image stored in file 'inputfile' with resolution increased by factor f in both dimensions. 'filename' must be a valid graphic file (jpg, gif, tiff,...
Computes the H-infinity optimal causal filter (indirect B-spline filter) for the cubic spline.
psi: the optimal filter psi(z) in a TF object
gopt: optimal value

Baseline Fit each column in "x".
There did not seem to be a similar function in th file exchange. This routine is simply a wrapper for two Matlab routines, interp1 and ginput.

prg is a semi-automated outlining program on an image. This program enable the user to manually select points on the image to form an outline. The user left click on the image once to make the image active and then left clicks on the
OGRE (Object-Oriented Graphics Rendering Engine) is a scene-oriented, flexible 3D engine written in C designed to make it easier and more intuitive for developers to produce applications utilising hardware-accelerated 3D graphics.
[psi gopt] = dfdesign_w_lmi(phi, w, d, n);
DFDESIGN_W_LMI computes the H-infinity optimal inverse FIR filter of phi(z).
The resulting filter minimizes the H-infinity norm of the error system
E_w(z) = [z^(-d) -...
This function transforms volume 'old_im' by means of affine transformation matrix 'M'. The output volume can be sub- and oversampled. The function makes use of interp3, so 'nearest', 'linear', 'spline', 'cubic' and fast ( * ) interpolation is...
[psi gopt] = dfdesign_w(phi, w, d);
DFDESIGN_W computes the H-infinity optimal inverse filter of a given filter phi(z).
The resulting filter psi(z) minimizes the H-infinity norm of the error system
E_w(z) = [z^(-d) -...
Anderson and Darling (1952, 1954) introduced a goodness-of-fit statistic to test the hypothesis that a random sample comes from a continuous population with a specified distribution function. It is a modification of the Kolmogorov-Smirnov (K-S)...
MOMS (maximal-order-minimal-support) functions give the least number of supports for a given approximation order L. The stringent requirement of number of supports is critical to real-time signal processing, which is why sinc (the kernel that...
GSP is a graphical user interface which takes x and y points as inputs, along with the order m, then outputs mth order splines between each of the x points. In most cases additional constraints are to be entered as well.
A simple m file for the triangle mesh subdivision using linear interpolation. The zip file includes four examples of subdivision.
