PiecewiseConstant
Defines data using a set of x-y data pairs
Description
The PiecewiseConstant
function defines the data using a set of x-y data pairs. Instead of linearly interpolating between the values, however, the PiecewiseConstant
function is constant when the abscissa is between the values provided by the user. The direction
parameter controls whether the function takes the value of the abscissa of the user-provided point to the right
or left
value at which the function is evaluated. Also available is right_inclusive
and left_inclusive
options, which will return the value of the function at the specified abscissa.
