Different size plotting matrices

Hi all, I want to ask how to plot 3D different size vectors?. Actually, there is 2 matrices (x,y) have the same dim. and the third has [ 1 : 2 ] <- this is time vector (delay matrix) I used mesh grid but it doesn’t work because of error in Z axis.

thank you for help.

We're not sure how or why you're using meshgrid().

Somehow get your various matrices and vectors into single column vectors representing x, y, and z. Then call plot3():

plot3(x, y, z, 'b*-', 'LineWidth', 2);

It will put a * at each data point in a 3-D plot and connect them with lines.

hi Mr/Mrs Analyst, how can plot the previous data with each delay separately? I mean x,y with 1, x,y with 2? like the attached figure

That's a surface, not a 3-D plot of points. So you get a 2D array for each one where the array values are the "height" of the surface above the plane, and then call surf().

Got it Thank you
