Matlab plot 3d matrix.

1. Link. I'm not sure if I fully follow your question, but here is my understanding. The first step is to find the coordinates of all points in the new coordinate system. For that you'll have to first subtract origin from all points and then convert all points to the local coordinate system. That conversion matrix should … contour (Z) creates a 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. contour (X,Y,Z) specifies the x and y coordinates for the values ... More Answers (1) Preallocate an array of zeros , using the optional argument to make it size 35x43x12. Use a loop to read the data from each file, and allocate the values into the array using some indexing . Note that MATLAB indexing is one-based, and is row-major: X (row,col,3rdDim,4thDim,...)

bar3 (z) creates a 3-D bar graph for the elements of z. Each bar corresponds to an element in z. To plot a single series of bars, specify z as a vector. For a vector of length m, the function plots the bars on a y -axis ranging from 1 to m. To plot multiple series of bars, specify z as a matrix with one column for each series. You need to read about sparse matrix. sparse saves only non-zero values and their respective indices. If you want to assign it into a 3D matrix, obviously you need to use full matrix. You cannot simply assign sparse to a 3D matrix. If you still insist on, you can save sparse into a cell, so that it can save your memory.

1. Given that your matrix is in X, it's as simple as: plot3(X(:,1), X(:,2), X(:,3), 'b.'); plot3 takes in three arguments as a base. The first argument are the x coordinates, the second are the y coordinates and the third are the z coordinates. Because you have all three coordinates conveniently in a matrix and each are in …

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.
