[35 points] In our lectures, we demonstrated that PCA has a close connection with the singular value decomposition (svd). Let us verify this connection. Take the first four columns in the iris data. Based on our understanding of the connection between PCA and SVD, obtain the following objects using the svd) function. Note that you cannot use any built-in function that performs PCA directly, however, you can use Plot the variances of the principal components in a decreasing order Obtain the first two principal components, and plot them on a figure, color the points with true species. Print the rotation matrix. [35 points] In our lectures, we demonstrated that PCA has a close connection with the singular value decomposition (svd). Let us verify this connection.
