Octave中的Sylvester功能

Question

I am trying to run a code in Octave written basically for Matlab.

One of the functions from this code file named - Sylvester(A,B,C) which is documented in Octave-forge as available is failing with following error.

error: 'sylvester' undefined near line 14 column 9

The octave version that I am using is 3.8.2.

I am new to Octave. Can someone suggest what extra I need to do in Octave so as to make this work?

Thanks in advance!

Answer 1

You need to update Octave. The function sylvester was only added in Octave 4.0.0 .

Answer 2

In Octave, for Sylvester function, they have used lyap(A,B,C) function for solving

AX+XB+C=0

type of optimization function.

Though, the original sylvester function is

AX+XB=C

I am not sure how they call both the functions as sylvester form.
