MATEXPM
Matrix Exponential
Block Screenshot
Contents
Description
The MATEXPM outputs the matrix exponential of a square matrix input computed by the Padé's approximants. The output is a square matrix with the same size of the input.
The equivalent of this block in Scilab is expm.
Parameters
Datatype(1=real double 2=Complex)
It indicates the type of the output. It support only the two types double (1) and complex (2). If we input another entry in this label xcos will print the message "Datatype is not supported".
Properties : Type 'vec' of size 1.
Default properties
always active: no
direct-feedthrough: yes
zero-crossing: no
mode: no
regular inputs:
- port 1 : size [-1,-1] / type 1
regular outputs:
- port 1 : size [-1,-1] / type 1
number/sizes of activation inputs: 0
number/sizes of activation outputs: 0
continuous-time state: no
discrete-time state: no
object discrete-time state: no
name of computational function: mat_expm
Examples
u = [1 2 3 ; 2 3 1 ; 4 2 1] y = [182.612 196.518 141.735 ; 172.973 190.770 133.577 ; 204.677 220.063 159.067]
Matrix Exponential example: expm([0 sin(t) ; sqrt(t) 0])
