BPF¶

Inputs¶

• x (real) - the input coordinate (x-axis)

Outputs¶

• y (real) - the output coordinate (y-axis)

Parameters¶

• xPoints (vector_real, default = [0, 1]) :

  the x-coordinates of the points forming the break-point function (the points must be arranged in ascending order and cannot contain duplicates)

• yPoints (vector_real, default = [0, 1]) :

  the y-coordinates of the points forming the break-point function

Description¶

This algorithm implements a break point function which linearly interpolates between discrete xy-coordinates to construct a continuous function.

Exceptions are thrown when the size the vectors specified in parameters is not equal and at least they contain two elements. Also if the parameter vector for x-coordinates is not sorted ascendantly. A break point function cannot interpolate outside the range specified in parameter “xPoints”. In that case an exception is thrown.
