Invert 3x3 Matrix block

To add a block to a model, double-click the canvas and start typing the block name. Then, select the block from the list.

Libraries:
Aerospace Blockset / Utilities / Math Operations

Description

The Invert 3x3 Matrix block computes the inverse of 3-by-3 matrix.

If det(A) = 0, an error occurs and the simulation stops.

Ports

Input

Port_1 — Input matrix

3-by-3 matrix

Input matrix to be inverted, specified as a 3-by-3 matrix.

Data Types: double

Output

Port_1 — Matrix inverse

3-by-3 matrix

Matrix inverse of input matrix, returned as a 3-by-3 matrix.

Data Types: double

Programmatic Use: Add Block

To add the block programmatically, use the add_block function with one of these library block paths as the source.

"aerolibutil/Invert  3x3 Matrix"

Example: add_block("aerolibutil/Invert 3x3 Matrix","myModel/myBlock",MakeNameUnique="on")
