Automatic differentiation is a technique for computing the derivatives of a function using the chain rule. Matlab objects make it easy to implement automatic differentiation. Note that this package is implemented in a rather old version of Matlab. You may need to edit it for newer versions.
An example of using automatic differentiation to compute the value and derivative of the Rosenbrock function at the point [1,2] is as...
Basic examples of using trapz and quad to evaluate the integral of two simple known functions between defined limits.
A for loop is used to loop over the upper limits of integration. The results are compared to show the greater...
Complex step differentiation (CSD) is a superior numerical differentiation approach. Normally, it is more efficient and accurate than finite difference appraoch. This package provides a way to improve the MATLAB fmincon function using the CSD.
Complex step differentiation (CSD) is a superior numerical differentiation approach. Normally, it is more efficient and accurate than finite difference appraoch. This package provides a way to improve the MATLAB lsqnonlin function using the CSD.
plot_lines(xin) - Plots vertical lines at points defined on the x-axis using red solid lines and the current y-axis limits using a single line handle
plot_lines(xin,[a b]) - Plots the lines from a to b
FileField Meta Refresh came about because a host I was using had a limits in place that prevented the uploading of files larger than 40M. To get around this I was submitting a small file with the same filename, uploading the actual file via ftp,...
Using this component, emails can be posted and received via SMTP efficiently. This object offers many enhanced features like mail attachments, backup SMTP servers in large number without any limits. It supports multiple recipients, allows any...
Estimates the signal width of data input, using definition: rho = cumtrapz(t,x.^2)/trapz(t,x.^2)
The integration limits go from mean(t)-w/2 and mean(t)+w/2; w is defined as the signal width, and gives the time at which rho...
The absorption coefficient can be obtained empirically by using Thorp's formula.Thie formula that used in the code is generally valid for the frequencies above a few hundred hz.The absorption coefficient is used to find the absorption loss part of...

User Relationship Limits extends User Relationships and provides the ability for site administrators to limit the number of possible relationships per user role.
Domain user edit is used to restrict access to edit users to only let users with the 'administer users' permission AND assigned to the same domain, using the Domain module, to edit the user.
To by-pass this restriction, you can assign...
Overview
Role Limits is a small, but useful, module that allows for users with proper permissions to set a limit on the number of users in a given role. Think of this module very much like "Maximum Node Population" in CCK only...
PIRETS is a module for Drupal which connects to real estate listing (MLS) providers using the RETS (Real Estate Transaction Standard) protocol and imports listings as Drupal nodes with CCK fields. PIRETS is the first step to building a truly great...
This module allows site administrators to set limits on the number of groups that users can create as well as the number of members that can join groups.
Note that the group member limit is calculated as the number of total group...
