MATLAB code to creat (simulate) a 3D truss by only having the number of bays, stories and frames and the length of each!

I am trying to write a code to get a few input information such as: number of bays, number of stories and number frames and the typical length for each of them. Basically, this is going to be a typical truss that has a same height in all the stories, same length for all the bays and same distance for all the frames. What I need in the output is: Matrix of node coordinates, Connectivity table, and element degree of freedom Matrix for the whole structure
