Question

Given the metrices A. B. and C. as defined in matlab. >>A = [1:4: 4:7; 10-1:7];b =[1 0 I 0]; What will be displayed to the screen from t>ping the following command in matlab. >> W"A*B* If 2 data streams x = {xl. x2. ...xN}. and y - {yI. y2, ....yN} have been given, the best fit least squares algorithm can be used to find the slope and y intercept as follows. Based on the 2 streams of data, form the lambda matrix and ? column vector in Matlab from the formula provided, and fill in the commands asked for in the questions that follow. Provide a matlab command for the M element of A. >>A(1, 1) = Provide a matlab command for the 1-2 element of A, >>A(1, 2)= Provide a matlab command for the 2-2 clement of A. >>A(2, 2)= Provide a matlab command for the 1-1 element of B. >>B(1, 1)= Provide a matlab command for the 2-1 element of B, >>B(2, 1)=
