I have been using subplot in MATLAB for a long time, but I thought, "Maybe it's time to try migrating to tiledlayout..." so I explored how to use "tiledlayout" in a way that is familiar to "subplot" ...

%function h=subtightplot(m,n,p,gap,marg_h,marg_w,varargin) % Functional purpose: A wrapper function for Matlab function subplot. Adds the ability to define the gap between % neighbouring subplots.
