Detailed Description

Functions for computing dimension-wise counts.

Function Documentation

apply()

template<typename Value_ , typename Index_ , typename Output_ , class Condition_ >

void tatami_stats::counts::apply	(	bool	row,
		const tatami::Matrix< Value_, Index_ > *	p,
		Output_ *	output,
		int	num_threads,
		Condition_	condition
	)

Count the number of values that satisfy the condition in each element of a chosen dimension.

Template Parameters

Value_	Type of the matrix value, should be numeric.
Index_	Type of the row/column indices.
Output_	Type of the output value. This should be at least large enough to hold the dimensions of p.

Parameters

	row	Whether to perform the count within each row. If false, the count is performed within each column instead.
	p	Pointer to a tatami::Matrix.
[out]	output	Pointer to an array of length equal to the number of rows (if row = true) or columns (otherwise). On output, this will contain the row/column variances.
	num_threads	Number of threads to use, for parallelization via tatami::parallelize().
	condition	Function that accepts a Value_ and returns a boolean. This function is also responsible for handling any NaNs that might be present in p.
