Numerical integration of a line integral. Write a function LineIntegral() in MATLAB for numerical integration of the line integral of a vector a along a given path between points A and B in space. The integral is (approximately) calculated as

where a_i and dl_i are given (approximate) values of a and dl at N points along the path (the input to the program are ai and dli, i = 1, 2, . . . ,N)
