I have solved a 2D time problem U(x,y,t), 0<=x,y<=L and 0<=t<=T, by FEM and i get
My question is how to write Matab code to see plot 1D for U solution of this problem if I choose for example : U(5,6,t) for all 0<=t<=T and U(x,5,0.15) for 0<=x<=L.
(To simulate 1D problem through a 2D problem ) this what i try write plot but it is not correct
find(x(m)==5 & y(m)==6)
Please i need help
