how to plot a matrix values in 3d plot
x=[0.2:0.5:0.8:1:1.5]
y=[0:0.2:0.4:0.6:0.8]
I got the matrix z=matrix(5x5) values from excel and each values correspond to x and y.

It would be nice to have the ‘z’ matrix as well, however in its absence, I will create one.
x=[0.2;0.5;0.8;1;1.5];
y=[0;0.2;0.4;0.6;0.8];
z = x*y.';;
figure
surf(x, y, z)
grid on
xlabel('x')
ylabel('y')
Use semicolons (;) not colons (:) to do vertical concatenation. They are two entirely different operators, and are used for entirely different purpoases.
