Web21 jun. 2024 · Mesh produces a 2D surface in a 3D volume, with the Z-axis being the value of the matrix at each X/Y point. If your solution's are truly 3D (a value defined at each X/Y/Z point), mesh cannot really plot any more than one 2D slice at a time (at least cleanly). Web4 jun. 2024 · y = linspace (0,0.3,51)'; [X, Y] = meshgrid (x, y); Z=x/ (1+y); surf (X, Y, Z); ylabel ('t'); xlabel ('x'); zlabel ('u (x,t)') It is showing error that matrix is singular and graph display is balnk. What is mistake with this code.Here in place of X it should be x is it so.
