sigTOOL: A MATLAB Toolbox for Biological Signals Analysis

This paper describes a software package for processing biological signals that has been designed to overcome this by assisting and promoting the sharing of laboratory-developed software. The package, called sigTOOL, has two components: [1] a software development environment designed to facilitate further programming by the end-user and [2] an application implemented through that environment to [...]

TopoToolbox: a set of Matlab functions for topographic analysis

The integration of spatial and non-spatial analysis software aims at providing a combination of the most efficient and powerful tools available in both environments (Brenning, 2008). There are various examples where this has been accomplished using access links between different software packages. JGrass, for example, provides integration of the statistic R package into the scripting [...]

FieldTrip – the MATLAB toolbox for EEG/MEG analysis

FieldTrip is a Matlab software toolbox for MEG and EEG analysis that is being developed at the Donders Institute for Brain, Cognition and Behaviour at the Radboud University Nijmegen, the Netherlands.
The FieldTrip toolbox includes algorithms for simple and advanced analysis of MEG and EEG data, such as time-frequency analysis, source reconstruction using dipoles, [...]

EigTool: Matlab Package for Computing Pseudospectra of Dense and Sparse Matrices

EigTool is a free MATLAB package for computing pseudospectra of dense and sparse matrices. It also provides a graphical interface to MATLAB’s built-in eigs routine (ARPACK) for large-scale eigenvalue computations. EigTool was developed from 1999 – 2002 by Thomas G. Wright at the Oxford University Computing Laboratory, under the direction of Nick Trefethen. The software [...]

ChebFun: Matlab Toolbox Numerical computation

The aim of the chebfun system is to “feel symbolic but run at the speed of numerics”. More precisely our vision is to achieve for functions what floating-point arithmetic achieves for numbers: rapid computation in which each successive operation is carried out exactly apart from a rounding error that is very small in relative terms [...]

Howto Produce Publication Standard Figure

I recommend the following tips for the best possible reproduction of High-quality figures. I divided this article into two parts. The first part is how to produce publication standard figures contains lines. The second part is talking about how to render image files for publications. I normally save these two settings in Matlab so that [...]

Howto Animate Graphs in Matlab

A Simple Example
1234567891011121314clear all; close all; clc;
f0 = 10;
N = 1024;
t = linspace(0,10,N); NFFT = 2^nextpow2(N);
fs = 1/(t(2)-t(1));
aa = 0.001:0.002:0.5; L = length(aa);
for kk = 1:L
    a = aa(kk);
    ff = f0 – a*t;
    y = cos(2*pi*ff.*t);
    periodogram(y,[],NFFT,fs); vline(f0); ylim([-50,2])
    F(kk) = getframe;
end
