Detailed Description

The C++ interface for Correlation Coefficient.

Returns the correlation coefficient of a set of elements

Function Documentation

ty af::corrcoef	(	const array &	x,
		const array &	y
	)

Correlation coefficient of two inputs of same size.

array a = array(seq(5));
array b = array(seq(5))-2*constant(1,5);
print(a);  //  0  1  2  3  4
print(b);  // -2 -1  0  1  2
float c = corrcoef<float>(a,b);
printf("%f\n",c); // 0.10

Parameters

[in]	x	input
[in]	y	input same size as x

Returns

Correlation coefficient between inputs
