Suppose we wish to estimate the discrete-time sequence s-1 2 3 2 Two discrete-time (DT) "observation" column vectors given below: 121 1 and V-21 2 3 Use these DT observation vectors to find the projection matrix PM. Calculate the error vector Plot the DT sequence along with its projection on plane formed by the two observation vectors and the error vector using subplot command of MATLAB. The plots has to be stem plots. Include a grid, labels for axes and a title for each plot. Plot the two DT observation vectors on two separate panels with subplot commands. The plots has to be stem plots. Include grid, labels for axes and title for each plot. Use the following command in your plot:s: Se Suppose we wish to estimate the discrete-time sequence s-1 2 3 2 Two discrete-time (DT) "observation" column vectors given below: 121 1 and V-21 2 3 Use these DT observation vectors to find the projection matrix PM.
