Syntax

public static double CosineSimilarity(
	double[] x,
	int xoffset,
	double[] y,
	int yoffset,

)

x: Type: SystemDouble
Array of parameters values which characterize first object.
xoffset: Type: SystemInt32
Offset of the parameters values which characterize first object.
y: Type: SystemDouble
Array of parameters values which characterize second object.
yoffset: Type: SystemInt32
Offset of the parameters values which characterize second object.
size: Type: SystemInt32
Number of parameters in characteristic.

Type: Double
