source · pub fn ddx_vector<F: Float, VECTOR: Vector<F, LENGTH>, const LENGTH: usize>(
component: VECTOR
) -> VECTOR
Expand description
Returns the partial derivative of component
with respect to the window’s X
coordinate. Returns the same result as either ddx_fine
or
ddx_coarse
, selection of which one is dependent on external factors.
