Yes. However you cannot plot a scalar against vectors, so one way to do it would be:
x1=[0, 0.5, 1.0];
y1=[2, 3, 6];
z1=[1] * ones(size(x1));
figure
plot3(x1, y1, z1)
grid on
This creates a vector for ‘z1’, and plot3 will plot it.
Similarly, if you want to plot a mesh or surf plot, create ‘z1’ as a matrix:
x1=[0, 0.5, 1.0];
y1=[2, 3, 6];
z1=[1] * ones(size(x1,2));
figure
mesh(x1, y1, z1)
grid on
Experiment to get the result you want.
