cosine function

Similarity measure (similarity), that is to calculate the similarity between individuals, the smaller the value of similarity measure, the smaller the similarity between individuals, the greater the value of similarity indicates the greater the

C language cos () function: Cosine valueheader file: #include The Cos () function is used to find the cosine value, that is, the ratio of the side length of the angle to the length of the hypotenuse, and the prototype is:

Title Description: Give you two vectors of the same size a B, to find their cosine similarity; returns 2.0000 if the cosine is similar to a non-method (e.g. A = [0] B = [0]).Example: Given a = [1, 2, 3], B = [2, 3, 4]. Returns 0.9926, given a = [0],
