◆ triangle() [2/2]

template<typename dtype >

dtype nc::random::triangle	(	dtype	inA = `0`,
		dtype	inB = `0.5`,
		dtype	inC = `1`
	)

Single random value sampled from the "triangle" distribution. NOTE: Use of this function requires using the Boost includes.

◆ uniform() [1/2]

template<typename dtype >

NdArray< dtype > nc::random::uniform	(	const Shape &	inShape,
		dtype	inLow,
		dtype	inHigh
	)

Draw samples from a uniform distribution.

Samples are uniformly distributed over the half - open interval[low, high) (includes low, but excludes high)

NumPy Reference: https://docs.scipy.org/doc/numpy/reference/generated/numpy.random.uniform.html#numpy.random.uniform

Parameters

inShape
inLow
inHigh

Returns: NdArray

◆ uniform() [2/2]

template<typename dtype >

dtype nc::random::uniform	(	dtype	inLow,
		dtype	inHigh
	)

Draw sample from a uniform distribution.

Samples are uniformly distributed over the half - open interval[low, high) (includes low, but excludes high)

NumPy Reference: https://docs.scipy.org/doc/numpy/reference/generated/numpy.random.uniform.html#numpy.random.uniform

Parameters

inLow
inHigh

Returns: NdArray

◆ uniformOnSphere()

template<typename dtype >

NdArray< dtype > nc::random::uniformOnSphere	(	uint32	inNumPoints,
		uint32	inDims = `2`
	)

Such a distribution produces random numbers uniformly distributed on the unit sphere of arbitrary dimension dim. NOTE: Use of this function requires using the Boost includes.

Parameters

inNumPoints
inDims	dimension of the sphere (default 2)

Returns: NdArray

◆ weibull() [1/2]

template<typename dtype >

		dtype	inA = `1`,
		dtype	inB = `1`
	)

Create an array of the given shape and populate it with random samples from the "weibull" distribution.

NumPy Reference: https://docs.scipy.org/doc/numpy/reference/generated/numpy.random.weibull.html#numpy.random.weibull

Parameters

inShape
inA	(default 1)
inB	(default 1)
