Returns an instance of this class. This method uses a weak cache of previously-created instances to reduce memory usage.

Parameters:

samples - The values in the set. samples[i] is the value of the ith sample point. Must be sorted (either increasing or decreasing). May be null. The array is not copied, so either don't modify it or clone it first.

unit - The unit for the samples. Must be compatible with the default unit. May be null.

error - The error estimate of the samples. May be null.

Throws:
