Complex Numbers .... coding ... need help

[Dan Bookwalter N8DCJ]

I have not messed with complex numbers in probably 30 years or more... I have a snippet of Matlab code that I need to wire up asap , I made a couple of feeble attempts and decided to ask the experts.

 

I need a wiring soluition for this:

 

exp(sqrt(-1)*angles)

 

I assume it is pretty simple?

 

TIA

There is the complex data type.  sqrt(-1) is just i.

Is this what you need?

 

Treats your angle array as the imaginary component of a complex number (with a 0 real value component).

 

Check out the help for Re/Im To Complex and Exponential Function.

Rewrite exp(i*v) to exp(i)^v, or in LabVIEW notation

 

LabVIEW 2010:

Complex rotation.vi

Orwire angle to a cos and sin function and then feed them both to a real amd imaginary parts to complex number

(e^{i\theta}=\cos \theta + i \sin \theta)
