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
