public static float[] subVecs(float[] a, float[] b)

Subtracts a vector from another vector

• Parameters:
• a — a vector of any length
• b — vector of the same or longer length which will be subtracted from a
• Returns: a vector the length of a representing a-b

public static float[] addVecs(float[] a, float[] b)

Adds two vectors

• Parameters:
• a — a vector of any length
• b — a vector of greater or equal length
• Returns: vector the length of a representing a+b

public static float[] multVec(float[] a, float scalar)

Multiplies a vector by a scalar

• Parameters:
• a — vector of any length
• scalar — any non-NaN float
• Returns: the vector times the scalar

public static float mag(float[] vec, int i)

Calculates the magnitude of a vector

• Parameters:
• vec — a vector of any length
• i — the length of the vector to consider (must be <= vec.length())
• Returns: the magnitude

public float mag(float[] vec)

Convenience method for mag(vec, vec.length)

• Parameters: vec — A vector of any length
• Returns: the magnitude
