SCALARPRODUCT(a,b)


DOTPRODUCT(a,b)


  • and are any two set values.

Description

  • This function shows the Scalar product value.
  • In   or  ,  and   are two set of values with same length.
  • Dot product is also called Scalar Product.
  • This product is an example of an Inner product.
  • Dot product is the algebraic operation which calculates with the two equal length values and gives the single value as result.
  • Here a and b are two set of values with any real numbers.
  • Also a and b are having same length of values.
  • The dot product of two vectors  and   is defined as:

  where   denotes summation notation and   is the dimension of the vector space.

Examples

  1. SCALARPRODUCT([2,3,4],[9,8,7]) = 70
  2. SCALARPRODUCT([3.2,4.5,10.3],[4,8,4.3]) = 93.09
  3. SCALARPRODUCT([-6,-15,21],[32.3,19.3,20.3]) = -56.99999999999994
