inertiaMatrix

Class: simscape.multibody.MassDistribution
Namespace: simscape.multibody

Compute inertia matrix

Since R2022a

Syntax

IM = inertiaMatrix(md)

Description

IM = inertiaMatrix(md) computes the inertia matrix of the provided simscape.multibody.MassDistribution object, md.

Input Arguments

md — Mass distribution

simscape.multibody.MassDistribution object

Mass distribution, specified as a simscape.multibody.MassDistribution object.

Output Arguments

IM — Inertia matrix

simscape.Value([I_xx I_xy I_zx; I_xy I_yy I_yz; I_zx I_yz I_zz],"mass*length^2")

Inertia matrix of the mass distribution, returned as a simscape.Value object that represents a 3-by-3 matrix with a unit of mass*length^2. The diagonal elements of the inertia matrix are the moments of inertia, and the off-diagonal elements of the inertia matrix are the products of inertia.
