matlab 3d surface plot from points

I have a predicted surface plotted in matlab and want to plot the real data in the same 3D space but don't know how. I am having trouble trying to make a surface plot out of given 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. You don't want too few points in the "grid" or it will appear jagged, but too … 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. Learn more about plot 3d sets Plotting two sets of 3D points on same graph. 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. ... How can I plot a 3D solid figure (not just 3d surface) Follow 47 views (last 30 days) lingfeng zhou on 18 Nov 2016. Plot the expression f as a surface. I have a matrix Nx3 where each row represents X,Y,Z coordinates of points. From the z components in the matrix "zz", the surf command will create a 3-D shaded surface. Defining the domain here is even trickier than for 2D. Improve the appearance of the surface plot by using the properties of the handle returned by fsurf, the lighting properties, and the colormap.. 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. 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. The actual command line will be in the format of surf(xx,yy,zz). Plot the surface using the surf command. This example shows one way to plot 3D surfaces. When I do this the 3D surface plot breaks down. 0 ⋮ ... Find the treasures in MATLAB Central … Here's a description of two easy ways to make surface plots in Matlab, including step-by-step instructions. I have managed to plot a surface plot which uses interpolation and fits … This is the point in which you will relate xx, yy, and zz together. Plotting high quality 3D surfaces from points.
