Hello, could I get a help with this programming hw Directions: Your m-files must be named ubitname_plot_forces.m and ubitname_force_sol.m as described in the tasks below, where ubitname is your UBITName. Your m-files must be uploaded to UBlearns before the due date & time. (Important: It is not necessary to ZIP any files!) You must write your own code and follow all instructions to get full credit. Except to test & verify your code, you are not allowed to use built-in MATLAB functions lu, mldivide (the operator), and inv (or similar), nor are you allowed to merely copy scripts & functions found on the Internet. For all functions, if a call to the function does not contain the proper number of input or output arguments (see functions nargin, nargout, narginchk, nargoutchk), then you must notify the user by throwing a suitable error message using MATLAB functions error or assert.
