# Special Vintage: Differential Equation Editor3

This week I feel like an archaeologist who just dug out a new species of dinosaur! I discovered the Differential Equation Editor...... read more >>

# From Symbolic to 亚搏国际网页3

I am recently visited the MathWorks Japan office and learned about interesting work done by my colleague Hitoshi Takeshita.... read more >>

# 亚搏国际网页 Debugger: Monitoring Variable Step Solver Performance3

A few months ago I introduced my favorite command to analyze the performance of a variable-step solver.... read more >>

# Why do we need Stiff ODE Solvers?2

I hope you have noticed the new MATLAB Central blog: Cleve's Corner. Cleve once said "stiffness is an efficiency issue." Let's explore this from a 亚搏国际网页 point of view by revisiting an article by Cleve in MATLAB News and Notes, May 2003: Stiff Differential Equations.... read more >>

# Continuous sample time inside For Each Subsystem2

Back in 2010, I wrote a post explaining how to apply a scalar algorithm to a vector using the For Each subsystem. At that time, only discrete algorithms could be vectorized that way. In R2011b, the For Each subsystem now supports continuous sample times.... read more >>

# Parallel Computing with 亚搏国际网页: Running Thousands of Simulations!7

Update: In MATLAB R2017a the function PARSIM got introduced. For a better experience simulating models in parallel, we recommend using PARSIM instead of SIM inside parfor. See the more recent blog post Simulating models in parallel made easy with parsim for more details.... read more >>

# Refining the Output of a Simulation11

Today I am pleased to share a post from regular guest blogger, Guy Rouleau.  Enjoy!... read more >>

# Modeling Mechanical Systems: The Double Pendulum8

Do you ever have to model mechanical systems?  Mechanical systems consist of bodies, joints, and force elements like springs.  In this post, I will show you how to model a double pendulum with base 亚搏国际网页 and using SimMechanics.... read more >>

# Challenge: Metronome and Cart Equations of Motion34

I haven’t
seen much activity on the Metronome Synchronization Challenge, so I want to provide a peak at the basis
for my solution.  I took the approach of modeling a pendulum, and then linking
its dynamics to the dynamics of a cart.  The challenge is choosing the right
coordinate systems to assign to each... read more >>
