Matlab plot 3d matrix.

Oct 10, 2012 · 3d plotting of a 2d matrix in matlab. I have an MxN matrix, Z, and some variable h. This matrix represents the points to a solution of a function f (x,y). h is the spacing between points. For instance: The domain is from 0 to M*h and the range is from 0 to N*h. I would like to make a 3d representation of the solution defined by the matrix. I would like to plot each slice of my 3d matrix to show differences across the third dimension. However I can only manage to plot them besides each other, and I would like a 3d plot where it is clear that the slices of the matrix are in fact stacked.

If you’re always on the hunt for cheap flights, you’re likely familiar with using Google Flights, Skyscan...Accepted Answer. In order to use plot () efficiently, you should prepare the data to call it just one time. plot () treats each column of 2D arrays as a separate line. So if you had, for example, a 3x4x5 matrix, you need 12 lines of 5 points. You should first permute the matrix and then reshape it to have all of the data in columns.

The trick is to form the right matrices so that this goes into plot3 correctly. How plot3 works is that you can either place single vectors in for your x,y,z values, or you can use matrices xMat,yMat,zMat instead. Each column of each matrix of xMat, yMat and zMat denote a single trace to be placed in your plot. Therefore, each column of xMat for each …
