Creating a mesh using vectors of x, y, and their corresponding z value

Hello,

I'm trying to plot a 3D mesh of z values based upon x and y coordinates. I have tried doing this in a variety of ways, and have gotten a variety of errors - that z must be a matrix, not a vector or a scalar. Adjusting this so that x is a 1xn vector, y is a 1xn vector, and z is a 3xn matrix, where z(1,n) = x, z(2,n)=y, and z(3,n) is populated with the corresponding z values. Attempting to run: mesh(x, y, z,'EdgeColor','black'); I received the error that data dimensions must agree (not surprising). When I try to run: mesh(z); it plots an incorrect surface. For 10 iterations of my code, there are ten sets of 3 data points - it plots the x value, the y value, and the z value, along each of their respective axis', connecting the plotted points for each data point/matrix entry.

Any suggestions? Please let me know if you would like to see more of my code. Thanks!
