How to write function for this Matlab problem?

Consider an integer n greaterthanorequalto 2. R^n is the set of vectors of the form x = (x_1, x_2, ..., x_n) where all the components x_i (t = 1, 2, n) of the vector are real numbers. The dot product x y between two vectors x = (x_1, X_2, ..., x_n) and y = (y_1, y_2 V_n) of R^n is defined as: x y = x_1 y_1 + x_2y2 +x_ny_n The projection of vector y onto a non-zero vector x is the vector p Element R^n such that: Write a function with the following header: where x, y, and p are a 1 Times n row vectors of class double that represent vectors of R^n and such that, p is the projection of vector y onto vector x. You can assume that each of these vectors contains at least two elements (i.e. n greaterthanorequalto 2), and that at least one element of x is non-zero. Test cases: >> p = my projection ([Theta, 1], (2, 4]) P = Theta 4 >> p = my_projection([2, Theta], (Theta, 1])
