Matrix Exponential in Labview

[Ian2]

Anybody know how to compute a 'Matrix Exponential' in labview? Either in the base package or an add-on toolkit. For a an explanation of the matrix exponential, see: http://zone.ni.com/devzone/conceptd.nsf/webmain/0CF7E24984DA7D9586256D720054FC07?opendocument

Which the only reference I can find on the web site.

Thanks, Ian Wall

I quickly looked at the document and I do not think you compute the matrix exponential.

It appears to be an identity. It just says that a matrix to some power can be expressed as an infinite sum. You can use the two interchangably in your calculations. For another explaination of matrix exponential,
S.O.O Math: Matrix Exponential

Perhaps I missunderstand your question. What kind of information were you going to get from the calculation and how did you want to use it?

Hi Jeremy,

Perhaps I should have been clearer: I have a requirement to compute the matrix exponential of a matrix as part of some state-space calcs. This is all part of a system simulation process - I was hoping for a vi which implements the matrix exponential. For example, in matlab there is a function expm() which does just that.

It looks like I'm on my own.
