How do you plot 3 dimensional data in Matlab?

plot3( X , Y , Z ) plots coordinates in 3-D space.

  1. To plot a set of coordinates connected by line segments, specify X , Y , and Z as vectors of the same length.
  2. 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.

How do you plot a two dimensional matrix in Matlab?

Direct link to this answer

  1. s = size(M);
  2. [z,x] = ndgrid(1:s(1),1:s(2));
  3. data = permute(num2cell(cat(3,x,M,z), 2),[3,2,1]);
  4. plot3(data{:});

How do you plot a matrix on a graph in Matlab?

figure A = adjacency(G); H = graph(A(1:30,1:30)); h = plot(H); To visualize the adjacency matrix of this hemisphere, use the spy function to plot the silhouette of the nonzero elements in the adjacency matrix. Note that the matrix is symmetric, since if node i is connected to node j, then node j is connected to node i.

How do you display a matrix image in Matlab?

Display Image of Matrix Data Create matrix C . Display an image of the data in C . Add a colorbar to the graph to show the current colormap. By default, the CDataMapping property for the image is set to ‘direct’ so image interprets values in C as indices into the colormap.

How do you convert a 2-D graph to 3D in MATLAB?

Direct link to this answer

  1. x = linspace(0, 1, 100); % Create Data (Independent Variable)
  2. y = [x.*exp(-8.0*x); -x.*exp(-8.0*x)]; % Create Data (Dependent Variable Matrix)
  3. figure(1)
  4. plot(x, y) % 2-D Wing Section.
  5. grid.
  6. figure(2)
  7. surf([x; x], [y(1,:); y(1,:)], [zeros(size(x)); ones(size(x))]) % Upper Half Of 3-D Wing Section.

How do you declare a 2D array in MATLAB?

Definition of Matlab 2D Array

  1. variable_name: It is a user-defined name we can assign any name that we want.
  2. size: Size is a function with help of size we can return the row vector that length corresponding to the size of Array.
  3. Same variable we used in the second syntax as shown.

What does Ndgrid mean in MATLAB?

The 1-D syntax, X = ndgrid(x) , returns a distributed array column vector X that contains the elements of the input distributed array x for use as a one-dimensional grid.

How do I convert a matrix to an image?

I = mat2gray( A , [amin amax] ) converts the matrix A to a grayscale image I that contains values in the range 0 (black) to 1 (white). amin and amax are the values in A that correspond to 0 and 1 in I .

How do I display an image with a subplot in MATLAB?

subplot divides a figure into multiple display regions. Using the syntax subplot(m,n,p) , you define an m -by- n matrix of display regions and specify which region, p , is active. For example, you can use this syntax to display two images side by side.
