partitionWithCurve¶

maelzel.distribute.partitionWithCurve(x, numpart, curve, method='brentq')[source]¶

Partition x in numparts parts following curve

Parameters:

x (float) – the value to partition
numpart (int) – the number of partitions
curve (BpfInterface) – the curve to follow. It is not important over which interval x it is defined. The y coord defines the width of the partition (see example)
excluded – any value

Return type:

list[float]

Returns:

the list of the partitions

Example

Partition the value 45 into 7 partitions following the given curve

>>> import bpf4
>>> curve = bpf4.halfcos(0, 11, 1, 0.5, exp=0.5)
>>> distr = partitionWithCurve(45, 7, curve)
>>> distr
array([ 11.        ,  10.98316635,  10.4796218 ,   7.89530421,
         3.37336152,   0.76854613,   0.5       ])
>>> abs(sum(distr) - 45) < 0.001
True
