openalea.hydroroot.length.fit_law(x, y, scale=0.0, k=1, s=0, **kwds)[source]#

Return a spline interpolation of y(x)

Parameters:

x – (float list)
y – (float list)
scale – (float) - number dividing x and y if > 0 (Default value = 0.)
k – (int) - degree of the smoothing spline (Default value = 1)
s – (float) - positive smoothing factor used to choose the number of knots (Default value = 0)
kwds – additional arguments see scipy doc of UnivariateSpline

Returns:

openalea.hydroroot.length.fit_length(csvdata, length='1e-4', k=1, s=0.0)[source]#

Fit a 1D spline from (x, y) csv extracted data.

Retrieve the values it will be applied to from the prop_in of the MTG. And evaluate the spline to compute the property ‘prop_out’

Parameters:

csvdata
length – number dividing data if > 0 (Default value = ‘1e-4’)
k – (int) - degree of the smoothing spline (Default value = 1)
s – (float) - positive smoothing factor used to choose the number of knots (Default value = 0)

Returns:
