DOTPRODUCT(a,b)
- and are any two set values.
and 
are any two set values.Description
- This function shows the Dot product of the given numbers.
- Dot product is also called Scalar Product.
- This product is an example of an Inner product.
- Dot product of two vectors is defined as and then a.b= sum i= 1 to n aibi= a1b1+a2b2+...anbn where Σ denotes summation notation and n is the dimension of the vector space.
