Matlab plot 3d matrix.

Vector and Matrix Data. plot3 (X,Y,Z) plots coordinates in 3-D space. To plot a set of coordinates connected by line segments, specify X, Y, and Z as vectors of the same length. To plot multiple sets of coordinates on the same set of axes, specify at least one of X, Y, or Z as a matrix and the others as vectors. Matrix Service News: This is the News-site for the company Matrix Service on Markets Insider Indices Commodities Currencies StocksJun 10, 2011 · I have a 6x6 matrix that I need to plot on an 3D graph. The elements 1-2-3-4-5 of the first column should be on the x axis, the elements 1-2-3-4-5 of the first row should be on the y axis, element 0,0 is NaN. I have a matrix with dimensions N by 3, for example 100 rows and 3 columns. Each row correspondds to the 3D location of a point, i.e., we have 100 points. I want to pot the 100 points and connect them as a surface.I would like to show several spheres in my 3D spaces, each with a different center location and radius. So I followed the tutorial by Matlab and I get the following result. The only problem is that I might have hundreds of spheres to plot so it won't be possible to write down hundreds of lines.

You cannot plot the entire data set on a surface. You can plot a slice of your 3d matrix as a surface, but not the entire data set. I would try scatter3 with color coding, it may end up looking OK. Start by something like this: Theme. Copy. [X Y]=meshgrid (1:40,1:180); A=randn (40,180,40); X=repmat (X,1,1,40);

Plotting 3D scatter plot from elements in a matrix. I have a matrix A with dimensions 47 x 4. I would like to plot the values in the matrix in a 3D plot. For e.g element A (4, 5) = 12 should be represented with x=4, y=5 and z= 12. Since, the values are non-uniform, I think a 3D scatter plot would be a good way to visualize the data.This example shows how to create a variety of 3-D plots in MATLAB®. Mesh Plot. The mesh function creates a wireframe mesh. By default, the color of the mesh is proportional to the surface height. z = peaks(25); figure mesh(z) Surface Plot. The surf function is used to create a 3-D surface plot.contour3 (Z) creates a 3-D contour plot containing the isolines of matrix Z, where Z contains height values on the x - y plane. MATLAB ® automatically selects the contour lines to display. The column and row indices of Z are the x and y coordinates in the plane, respectively. example. contour3 (X,Y,Z) specifies the x and y …Plotting 3D scatter plot from elements in a matrix.

Now i want exactly the same, but only with discrete points. already tried scatter3 but it needs 3 vectors, all of the same length. Basically I need something like stem3 (x,y,Z) but without the stems. Is there really no solution?There is not much heat to plot in that small data set. You might just visualize it with plot3 () and make the markers somewhat large. If you want to interpolate between the few discrete points, you can use scatteredInterpolant. F = scatteredInterpolant (x,y,z,v) creates a 3-D interpolant of the form v = F(x,y,z).

R = sqrt(X.^2 + Y.^2) + eps; The matrix R contains the distance from the center of the matrix, which is the origin. Adding eps prevents the divide by zero (in the next step) that produces Inf values in the data. Forming the sinc function and plotting Z with mesh results in the 3-D surface. Z = sin(R)./R; Specify the colors for a surface plot by including a fourth matrix input, C.The mesh plot uses Z for height and C for color.
