Hello,

I writing work on High School on topic IIR filtres and I need to create matrix of order 0.

In matlab:
p_0_NDP = []
p_0 = Omega_n * p_0_NDP;


In SMath studio?

x:#clean# - does not work


Thank you for help.

ZeroMatrix: like this

But it is not. If I insert M(0) is length matrix 1, but I need length matrix 0

I don't believe SMath supports empty Matrices.

Can you upload an example of what you're trying to accomplish?

We might be able to help implement it a different way.

You can send e-mail adress on you? I need help about SMath studio functions. Thank you.

A matrix of order zero is a "zero matrix"
If you want it rectangular from the fx menu
'Ones(3,5)' ,,,, then of any value: *1.23456789=

Example for declaration and use of an empty matrix:

Awesome. Thanks, Martin. I did not know that empty matrices were supported.

... a more elegant way to "skin the cat".

... technical matrix

At this point, you know how to create a "zeromatrix".
Visit "Samples => PseudoInverse" few days ago,
This type of matrix: you fill-in manually.
=====================================================

The other style matrices construct by themselves from their
governing algorithm. Download the attached work sheet.
I may be wrong but I would think your IIR filter is one of
this type matrix that constructs around the IIR algorithm.
