Polar plot after bilinaer interpolation

[Anonymous]

I am having a 2D arrayof complex numbers from Fourier transform. I
would like to plot these in a Polar plot after bilinear interpolation.
How is this possible?

Thanks

Hello,

What data type do you have after bilinear interpolation? If the only problem you have is in plotting a complex number on a polar plot, you could follow these steps:

1)  Use the 'Complex to Polar' VI (Programming>>Numeric>> Complex in the functions palette) to get the magnitude and phase values.

2)  Use the 'Bundle' function (Programming >> Cluster, Class, & Variant) to build a cluster consisting of these two values.

3)  Build an array of these clusters of polar values. You can then wire the array to the 'Polar Plot' VI (Programming >> Graphics & Sound >> Picture Plots) to plot them.

I hope this helps.
