MATLAB/ Programing logic definitions

A) Provide the Matlab code that would define a column vector containing 20 equally-spaced values between 24 and 90.

B) Provide the Matlab code for replacing the circled value in myMat, shown below, by two times its value (using multiplication by the original value)

C) The width of a rectangle can be calculated by dividing its areaby its length. Assume that two vectors called recArea and recLength contain theareas and lengths of several rectangles. Provide the Matlab code for calculating and storing the widths in the variable recWidth

D) The speed of a vehicle is stored in the numerical variable speed and its units (as character data) are stored in the variable unit. Provide the Matlab code that assigns a variable named label(of character data) to contain the speed in exponential notation with 3 digits past that decimal point followed by its units

E) Assume that x and y are defined and hold real scalar values. What is wrong with this matlab syntax? y = 2x + 4y^2

clearly show how you would fix it below.
