How to create a mesh for the following vectors: X= vector from -20 till 20 with increment of 8 Y=vector from -10 till 10 with increment of 4 Z= (sin X)*(sin Y) None of the other options rangeX=-20:8:20: range Y--10:4:10; [X,Y] meshgrid (rangeX, range Y); Z=sin(X).* sin(Y); mesh(X,Y,Z) the above the above X=-20:8:20: Y--10:4:10: [X,Y]=meshgrid (rangeX, range Y); Z=sin(X). *sin(Y); mesh(X,Y,Z) rangeX=-20:8:20; range Y=-10:4:10; [X,Y]=meshgrid (rangeX, range Y); Z=sin(X).sin(Y); mesh(X,Y,Z) the above the above
