# Interpolating unknows from polynomial curve

Posted on 2014-12-17

Hi,

I'm am trying to script an existing workflow and I am struggling with the last part.

The users have a standard curve of points as part of the data (x = percentage, y=value) and in an external software (Prism, GraphPad) utilise a 6th order polynomial non-linear regression to utilise that curve and then interpolate unknowns from that.

I have my x and y in 2 arrays ready to go.

In trying to recreate this I have been having a try with Math::Polynomial but the interpolate function of that seems to be using the curve data to predict the polynomial needed so I am a little confused.

Does anyone have a hint as to how best to approach this in perl by reading in curve data then reading out the unknowns?

Thanks
