blkdiag in Labview

[Markanbl]

Hi all, 

I'd like to know is there a special VI that would correspond to blkdiag in Matlab, to create a block diagonal matrix from other matrices or do I have to go the long way around and add one by one using Set Submatrix?

Thanks!

Hi Mark,

I don't think you will find a LabVIEW function for this.

But it also looks like a simple autoindexing loop might be the most complicated you need to program this on your own…

Hey Markanbl,

No there is no special VI but you can use the blkdiag command.

In LV the the command is " function y = blkdiag(varargin)"

add it in "Matlab Script" area.

In addition a short kB for Matlab -> LV communication

I'd like to use MathScript but I can't, apparently MathScript is a lot slower than the rest of LabView so I have to do everything "manually".

Thank you
