Can you write Matlab Code to solve please

Consider the diagram shown below. It depicts a simple bridge and a HS 15-44 truck live load.
Write a program that will compute and visualize the influence lines of bending moment and
shear force at points C for the two cases below, due to the influence of moving live load HS 15-
44. Note that A1, A2, A3, and A4 are support points. Take L1= 20 ft, and L2= 15 ft, 11 = 20 ft,
12 = 14 ft, and F=12k. Note that there are hinges at B1 and B2. State any reasonable
assumptions.
