could someone please help me with my problem, I am still a beginner in using MatLAB. I have a set od stress values in a beam. Each stress value is computed at a specific point with it's coordinates x and y. What I want is to plot a contour plot of the stresses in the beam, where the exact stress is located at point (x,y) in the beam. So, basically I have 3 vectors with 2 of them being the x and y coordinates and the third being the value at the point. I need to plot a contour plot with this data. Any help would be appreciated.
