Datapoints

% [Data, Labels] = ReadSpice(filename)%% Data is an MxN matrix containing the values of the M variables% at each of the N datapoints.%% Labels is a M-vector with the Mth label corresponding to the% Mth row in Data%% This script has been tested on raw (-r Out.raw) data from% ngspice-rework17.%%...

[VINDX FRACDIM V_SIGMA COVERSIZE] = varIndx(LOW,HIGH) LOW is a column vector of the lowest price in the bar (second, minute, etc). HIGH is a column vector of the highest price in the bar. VINDX is the variation index of the data. FRACDIM is the fractal dimension of the data. V_SIGMA is the...

A polar plot script that allows selection of axis limits by the user, including negative radial limits. It is particularly appropriate for logarithmic data.A known limitation is that datapoints outside the radial limits will still be drawn.

IMPLOT2 may be used to plot implicit functions of exactly two variables.It uses a similar approach to IMPLOT (by Arthur Jutan), but extends the capabilities of IMPLOT to allow the specification of one or more lineseries properties: e.g. line width, line color, line style etc. It can also return a...

clickfit_OH.m lets you mouse-click a series of datapoints on top of a (noisy) scatterplot and returns a spline or polynomial regression through the clicked dataseries. In addition the clicked series itself is returned.clickfit_OH.m uses an altered version of ginput.m (ginput_OH.m) that from the...

For vectors, Y = RUNMEAN(X,M) computes a running mean (also known as moving average) on the elements of the vector X. It uses a window of 2*M+1 datapoints. M an positive integer defining (half) the size of the window. In pseudo code: Y(i) = sum(X(j)) / (2*M+1), for j = (i-M):(i+M), and...

I started with Adam Wyatt's FROG program (on this website) but added to it and edited it beyond recognition. I did, however, subtract one useful feature: This program, as written, is SHG-FROG and GRENOUILLE only!! (Adam Wyatt's program was more general.)--> The program "prepFROG" takes a raw...

This is a robust and accurate circle fit. It works well even if datapoints are observed only within a small arc. This circle fit wasproposed by G. Taubin in article "Estimation Of Planar Curves, Surfaces And Nonplanar Space Curves Defined By Implicit Equations, With Applications To Edge And Range...

This function will perform a local regression at the given points. Using the data at hand. You will need to input a spanwidth which will tell the function how many datapoints he will use in the local regression at each evaluation.Example...

This is a robust and accurate circle fit. It works well even if datapoints are observed only within a small arc. This circle fit was proposed by V. Pratt in article "Direct least-squares fitting of algebraic surfaces", Computer Graphics, Vol. 21, pages 145-152 (1987). It is more stable than the...
