# matlab 3d surface plot from points

I would like to create something that resembles a surface plot, but I can not convert my Z into a matrix. I'm having trouble plotting a curve/surface of best fit through data points. Even in the absence of the plot3 command, just adding the hold on;/hold off; causes the surface plot to break down into a 2D heatmap. Learn more about plot 3d sets This is the point in which you will relate xx, yy, and zz together. Plot the surface using the surf command. I have a matrix Nx3 where each row represents X,Y,Z coordinates of points. Description. When I do this the 3D surface plot breaks down. You don't want too few points in the "grid" or it will appear jagged, but too … Here's a description of two easy ways to make surface plots in Matlab, including step-by-step instructions. Plot the expression f as a surface. ... How can I plot a 3D solid figure (not just 3d surface) Follow 47 views (last 30 days) lingfeng zhou on 18 Nov 2016. Vote. 3D surface plot from for loop. Learn more about 3d plots, surface plots, surface graphs from points Learn more about surf, plot, 3d, 3d plots, for loop I have managed to plot a surface plot which uses interpolation and fits … This example shows one way to plot 3D surfaces. Defining the domain here is even trickier than for 2D. The meshgrid command is vital for 3D surfaces! surf draws a colored parametric surface using a rectangular grid defined by X and Y coordinates (if {X,Y} are not specified, this grid is determined using the dimensions of the Z matrix) ; at each point of this grid, a Z coordinate is given using the Z matrix (only obligatory data).surf has been created to better handle Matlab syntax. I am having trouble trying to make a surface plot out of given points. Plotting two sets of 3D points on same graph. I have z - matrix of 9 data points, which correspend to different combinations of values from an x-vector of 3 and a y-vector of 3. Thxs. Surely, there must be a way to co-plot points onto a 3D surface plot? Improve the appearance of the surface plot by using the properties of the handle returned by fsurf, the lighting properties, and the colormap.. I want to create a surface plot by using the custom equation from variable ft and create surface from it that will fit to the data. Basic 3D Surface Example using SURF. From the z components in the matrix "zz", the surf command will create a 3-D shaded surface. The actual command line will be in the format of surf(xx,yy,zz).
