tuple_histo_range — Calculate the value distribution of a tuple within a certain value range.
gray_histo_range calculates the value distribution Histo
of the Tuple within the value range [Min,Max].
The values for Min and Max are
rounded down to the next integer if all entries of the Tuple are
of type integer. The value range is divided into NumBins
bins of the same size, which is returned in BinSize. If a value
lies between two bins the value is assigned to the smaller bin.
If the Tuple has entries of type real
. If all entries are of type integer the size of a bin is
computed with
.
If any of the input tuples is empty, an exception is raised.
If all the data of the Tuple are of type integer the value
of BinSize may cause the following effects:
For BinSize > 1 multiple consecutive numbers are
assigned to the same bin. If BinSize is no integer the numbers
are distributed uneven among the bins, e.g., for
BinSize = 1.5 the first and second number are assigned
to the first bin, the third number is assigned to the second bin, and the
fourth and fifth number are assigned to the third bin. This becomes
noticeable in several peeks in the histogram Histo. If
BinSize < 1 some classes are not assigned by any
number, e.g., for BinSize = 0.5 the first number is
assigned to the first bin and the second number is assigned to the third bin.
The histogram Histo shows some gaps, which resembles the
structure of a comb.
If the Tuple has entries of type real and
Min = Max, all entries of the corresponding value are
assigned only to the first bin.
Tuple (input_control) number-array → (real / integer)
Input tuple.
Min (input_control) number → (real / integer)
Minimum value.
Max (input_control) number → (real / integer)
Maximum value.
Restriction: Max >= Min
NumBins (input_control) integer → (integer)
Number of bins.
Restriction: NumBins >= 1
Histo (output_control) histogram(-array) → (integer)
Histogram to be calculated.
BinSize (output_control) real → (real)
Bin size.
If the parameters are valid, the operator tuple_histo_range
returns the value 2 (H_MSG_TRUE). If necessary an exception is raised.
