Transformation matrix: We consider the vector space, in which we define the line y = ax, where a is a given positive coefficient. Show (using a diagram) that function that takes a vector and project it (orthogonally) on the line is indeed a linear map Compute the matrix of this linear map A Using Matlab, compute the projections of the vectors (2, 1), (-1, 0), (4, 3), (-0.5, 1), (3, -2.5) on the line L y=ax, with a = 0.2, using the matrix A that you defined above Using the scatter function (in Matlab), plot the vectors defined above and their projections on the line L
