 Bigger Bigger  Smaller Smaller  Reset Reset

Hello!
I am a new member in this forum, and am a beginner in programing to arduino ... I wanted to know how to declare a matrix and its inverse and its transpose... etc
Indeed, I want to make a small program for controlling the level of liquid in a tank that needs a idetification real-time parameters of the mathematical model of the controlled system. (I use methods of identifying where there are many matrix computation)..!!
help me I'm lost!!!! :-/

Hi,

You've posted on the wrong forum. You are on the french forum.
You'd better post on the software/syntax & programs forum.

As far has I know, there is no library for matrix computation. But matrices are defined using arrays and you can write your own operators.

Par contre pour ton histoire de produit ou de somme, il faudra  expliquer ce que tu veux obtenir et à partir de quelles données.

merci pour ta reponce jean-François;
moi je voulais utiliser une méthode de moindre carrées pour faire l'identification des paramètres de mon système (mais en temps réel!). danc il faut faire le transposé le produit ainsi que l'inverse de la matrice!!!! c'est ça le problème!!!!!!
