linterp(x0, x1, x, y0, y1, *, inf_value=None)

Linearly interpolate y between y0 and y1 based on x’s position.

Parameters:

• x0 – Start of x range.

• x1 – End of x range.

• x – Value to interpolate at.

• y0 – Y value at x0.

• y1 – Y value at x1.

• inf_value – Value to return when x1 is infinity (default: y0).

Returns:

Interpolated y value.

Return type:

float

Example:

>>> linterp(1, 3, 2, 2, 4)
3.0
>>> linterp(1, float('inf'), 2, 2, 4)
2.0
>>> linterp(1, float('inf'), 2, 2, 4, inf_value=4)
4.0
