FAQs

Can you make a 3-D matrix in MATLAB? ›

You can create a multidimensional array by creating a 2-D matrix first, and then extending it. For example, first define a 3-by-3 matrix as the first page in a 3-D array. Now add a second page. To do this, assign another 3-by-3 matrix to the index value 2 in the third dimension.

How to plot 3-D data in MATLAB? ›

To plot a 3D surface from a data file in MATLAB, you will need to have the data file open in MATLAB. Once you have the data file available, you can use the plot3 command to plot the data. The plot3 command will create a 3D plot of the data. You can also use the surf command to create a 3D surface plot.

How to plot matrix elements in MATLAB? ›

plotmatrix( X , Y ) creates a matrix of subaxes containing scatter plots of the columns of X against the columns of Y . If X is p-by-n and Y is p-by-m, then plotmatrix produces an n-by-m matrix of subaxes.

How to make a three-dimensional matrix? ›

For a 3-dimensional array, create a 2D matrix first and then extend it to a 3D matrix. We can also use a function called cat Function to create multidimensional arrays.

How to create 3-D geometry in MATLAB? ›

Use multicuboid , multicylinder , or multisphere to create a 3-D geometry. Then assign the resulting geometry to the Geometry property of the model. For example, create a PDE model and add the following geometry formed by three spheres to the model. model = createpde; gm = multisphere([1,2,3]); model.

How to generate a 3D model in MATLAB? ›

Which command is used to plot a 3-D surface in MATLAB? ›

surf( X , Y , Z ) creates a three-dimensional surface plot, which is a three-dimensional surface that has solid edge colors and solid face colors. The function plots the values in matrix Z as heights above a grid in the x-y plane defined by X and Y .

How to plot a 3-D graph in MATLAB using Excel data? ›

The following example will illustrates how to do that:
  1. % Read the data points as a matrix.
  2. T = readmatrix('3DPlot.xlsx');
  3. % Create a meshgrid for plotting.
  4. [xq,yq] = meshgrid(0:.2:11.5, 0:.2:7.6);
  5. % Interpolate the points using griddata function.
  6. vq = griddata(t(:, 1), t(:, 2), t(:, 3),xq,yq);
  7. % Plot the surface.
