Write a Matlab function to calculate forces in each member in a simple Pratt or Howe Truss $($only one is sufficient$)$ as shown in Figure. $1.$ The user should be able to enter external loads, and the program should calculate the forces on each member. The results can be shown in a table. Alternatively, the results can be displayed on the diagram numerically or colorimetrically, as shown here:

Compression $($red$,$negative$).$ Tension blue, positive$).$ Reaction forces $($green$).$
