discretize Function: Group numeric data into bins or categories
The discretize function groups numeric data into bins. By default the bins are
numeric, and discretize returns indices describing the bin placement of each
element. However, the bins also can be categories, in which case discretize returns a
categorical array.
Descriptive Statistics: Omit NaN values in basic statistical calculations,
including max, min, mean, median, sum, var, std, and cov
The following functions now have flags to include or omit NaN values in numeric
computations: max, min, mean, median, sum, var, std, and cov.
ismembertol and uniquetol Functions: Perform set comparisons
using a tolerance
The ismembertol and uniquetol functions perform set operations using a tolerance.
These functions are useful in situations where floating-point round-off errors occur in
calculations.
Random Numbers: Generate random numbers using the double-
precision, SIMD-oriented Fast Mersenne Twister (dSFMT) algorithm
The dSFMT random number generator algorithm provides a faster implementation of
the Mersenne Twister algorithm. For more information about available random number
generator algorithms, see “Creating and Controlling a Random Number Stream”.
nearestNeighbor Function: Determine nearest alphaShape
boundary point
The nearestNeighbor function for alphaShape determines the nearest boundary point
on the alpha shape for a specified query point.
