I'm not sure how the set up the function to get a scalar value.

Problem 4 Write a user-defined MATLAB function that determines the dot product of two vectors. For the function name and arguments use Da.r). The input arguments to the function are two vectors (any size). The output D is the result (a scalac). Do not use dot building function. Make sure to usc for loop (either while or foo) Call this function from your homework file to determine the dot product of a. Vectors a 3i + 1 1 j and b 14i-7.3j Dot product: The dot product of two vectors a l,., a and bIb, . b] is defined as a bab For example a [1,3,-5]and b [4,-2,-1]a b (1)(4) + (3)(-2) + (-5)(-1) 4-6+5 3 b. Vectors c6i+ 14.2 + 3k and d 6.3i-8i-5.6k 13
