Have you ever had one of those days... ?

The Explanation
When I see things like that, my first reflex is usually to turn on most of the items in the Display menu. In this case, displaying the port... read more >>

# Improved Behavior of Auto Tolerance in R2017a

Are you familiar with the meaning of auto for the Absolute tolerance of Simulink variable-step solvers?
In R2017a, we decided to change the meaning of auto for the Absolute Tolerance... If your model... read more >>

# Simulink Debugger: Monitoring Variable Step Solver Performance2

A few months ago I introduced my favorite command to analyze the performance of a variable-step solver. This week, I will introduce how the Simulink Debugger can be used for a deeper analysis of... 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 Simulink point of view by revisiting an article by... read more >>

# THE Most Useful Command for Debugging Variable Step Solver Performance2

Today I want to share a trick I often use to determine if a variable step simulation runs as fast as it should. Visualizing the steps taken by a model To begin, save the simulation time data.... read more >>

# Different Results in Accelerated Mode Versus Normal Mode8

By Guy Rouleau This week I received a large model giving different results when used as a referenced model in Accelerated mode, compared to the Normal Mode. To give you an idea, the top model in... read more >>

# Wrong Answers and Gimbal Lock6

By Guy Rouleau I received a request last week where the code generated using Real-time Workshop was giving different answers from the original simulation. This type of requests is the one that... read more >>

# Did I just get a different answer?3

As part of any well designed Model Based Design work-flow, you need to ensure that you get the expected results from your simulation. You might want to evaluate the effect... read more >>
