On this π day 2024, I decided to tag along with Mike Croucher from The MATLAB Blog and show one way to compute π.While Mike went for advanced maneuvers involving the MATLAB AI Chat Playground,... read more >>
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 >>
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 >>
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 >>
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 >>
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 >>
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 >>
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 >>
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 >>
