LineModel

sans.models.LineModel

Provide Line function (y= A + Bx) as a BaseComponent model

class sans.models.LineModel.LineModel

Bases: sans.models.BaseComponent.BaseComponent

Class that evaluates a linear model.

f(x) = A + Bx

List of default parameters:

A = 1.0 B = 1.0

calculate_ER()

clone()

Returns a new object identical to the current object

evalDistribution(qdist)

Evaluate a distribution of q-values.

• For 1D, a numpy array is expected as input:

  evalDistribution(q)

where q is a numpy array.

• For 2D, a list of numpy arrays are expected: [qx_prime,qy_prime], where 1D arrays,

Parameters:qdist – ndarray of scalar q-values or list [qx,qy] where qx,qy are 1D ndarrays

is_fittable(par_name)

Check if a given parameter is fittable or not

Parameters:par_name – the parameter name to check

run(x=0.0)

Evaluate the model @param x: simple value @return: (Line value)

runXY(x=0.0)
