how to create vector X(n) = [x(n) x(n-1) x(n-2).........x(n-N+1) in labview

[rashi]

i want to create an input signal vector X(n)  = [x(n) x(n-1) x(n-2).........x(n-N+1)

Hi Rashi,

I think you need to read LabVIEW Basic -1. First read this all these issues will get resolved automatically.

This question is quite ambiguous, because you don't really define anything, but you could try "array subset" and "reverse array".

Can you give an actual example of an input array and desired output?

i am implementing variable step size least mean square filter equation in labview

output error  equatyion e(n) = d(n)-X'(n)W(n) where X(n) is input signal vector X(n) = x(n) x(n-1) ...............x(n-N+1), ' denotes transpose.
