orthax.polynomial.polyline(off, scl)Source

Returns an array representing a linear polynomial.

Parameters:

• off (scalars) – The “y-intercept” and “slope” of the line, respectively.

• scl (scalars) – The “y-intercept” and “slope” of the line, respectively.

Returns:

y (ndarray) – This module’s representation of the linear polynomial off + scl*x.
