Hi All, I am trying to plot the temperature distribution in a rectangular cross-section of slab subjected to fire. I have the nodal co-ordinates of all the elements of the cross-section as well as temperature at each nodes. When I plot this distribution using patch command in a loop in Matlab R2015b it works completely fine and gives great result. However, the same set of statemens and command when I execute in Matlab R2016a, it gives me an error. The command I use in a loop are: for e=1:nel XX = [X2(e,1) X2(e,2) X2(e,3) X2(e,4) X2(e,5)]; YY = [Y2(e,1) Y2(e,2) Y2(e,3) Y2(e,4) Y2(e,5)]; TT = [T2(e,1) T2(e,2) T2(e,3) T2(e,4) T2(e,5)]; patch(XX,YY,TT); hold on; end where, nel = number of elements X2 is a nel x 5, array with X-coordinates of the nodes of an element Y is a nel x 5, array with Y-coordinates of the nodes of an element T2 is a nel x 5, array with temperatures of the nodes of an element There are five columns in X2, Y2 and T2 is to complete polygon (rectangle) for patch command i.e., X2(e,5) = X2(e,1); Y2(e,5) =Y2(e,1); and T2(e,5) = T2(e,1) I tried to look for this issue but couldn't find any guidance. Any help would be appreciated
