I have a problem with plotting my numerical solution in L-shape domain.
I descritzed the system and using the natural rowwise order of unknowns.
For example, I ordering the system as below:
1 2 3 4 5 6 7 8 9 10
11 12 12 13
14 15 16 17
Then how do I visualize these solution which made by just a single column ?
In my opinion, I need to use "reshape" function. But I don't know how I approach the problem.
I attached one related picture that I want.
Thanks in advances
