AT&T LTE 9:22 AM 28% L--+ Matlab_exercises 2 DOC 31 KB Basic Array Syntax and Manipulations Close The following exercises are meant to be answered by a single MATLAB command. The command may be involved (i.e., it may use a number of parentheses or calls to functions) but can, in essence, be solved by the execution of a single command. If the command is too complicated, feel free to break it up over two or more lines. Given x - 13 1 579 2 61, explain what the following commands "mean" by by summarizing the net result of the command a. x (3) b. x (1:7 C. x(1:end) d. x(1:end-1) f. x(1 6211]) g. sum (x) 2. Given the array A2 4 1 6 7 2 3 5 9], provide the commands needed to a. assign the first row of A to a vector called x1 b. assign the last 2 rows of A to an array called y c. compute the sum over the columns of A d. compute the sum over the rows of A e. compute the standard error of the mean of each column of the s defi divid number o eiements usea to compute the mean.)
