Do this in MatLab please

It is straightforward to reach V_R1 = V_1 R1/R1 + R2 (a) Generate a Matlab Code to calculate the voltage across the Resistor R1 using the equation above. (b) Find out how to represent or produce a square wave of 100Hz having a peak-to-peak voltage of 20V (-10V to 10 V) in MATLAB. (c) If the V_1 is the square wave produced in (b), show V1 and V_R1 in the same graph. (d) Find out how to represent or produce a sine wave of 100Hz having a peak-to-peak voltage of 20V (-10V to 10 V) in MATLAB. Assign V1 as this sine wave, and plot V1 and V_R1 in one graph. (Each of the curves in the same plot should be distinguishable by both color and line-marks. This requirement applies to all figures that have multiple functions plotted in the same graph)
