Function Documentation

void cross_corr	(	int	n,
		real	f[],
		real	g[],
		real	corr[]
	)

fft cross correlation algorithm. Computes corr = f (.) g

Parameters

[in]	n	number of data point
[in]	f	First function
[in]	g	Second function
[out]	corr	The cross correlation

void many_cross_corr	(	int	nFunc,
		int *	nData,
		real **	f,
		real **	g,
		real **	corr
	)

fft cross correlation algorithm.

Computes corr[n] = f[n]i g[n][i], that is for nFunc pairs of arrays n the cross correlation is computed in parallel using OpenMP.

Parameters

[in]	nFunc	nuber of function to crosscorrelate
[in]	nData	number of data point in eatch function
[in]	f	2D array of first function to crosscorrelate
[in]	g	2D array of second function to crosscorrelate
[out]	corr	2D array of the cross correlations
