Problem 4 Write a user-defined MATLAB function that determines the dot product of two vectors. For the function name and arguments use D7 = da rofmu. The input arguments to the function are two vectors. The output D is the result (a scalar). Do not use dot building function. Make sure to use for loop. Use the function dotpro for determining the dot product of a. Vectors a = 3it 1 1) and b = 14i-73j b. Vectors c =-Gi + 14.2j + 3k and d = 631-8-5.6k , al and b = [ h, b> , bu is defin D1 abi ed as a,b= Dot product: The dot product of two vectors a = [a,, a,, 2,-1] a 2) + (-5)(-1) = 4-6 + 5-3 r example a=
