Write a MATLAB command that creates a row vector u that has the elements: cos( 3e y 19π 4 TT -2e, log10 (210), -60, 4|sin (-5)| Where | sin(x) is the absolute value of the sin(x). Then write the command to find the maximum value of v. 2b. Write MATLAB commands that assign 7 to variable x and 11 to variable y, create a column vector w that has the following elements, and then compute the average value of the elements: x! In(2y + x), √√x² + y², √(x + y)²-(y - x)² Where x! is factorial of x, for which you can use MATLAB built-in function, and ln(x) is the natural logarithm of x.arrow_forward3.3 only pleasearrow_forward
