I have obtained a 3D matrix A (:,:,3) for the geometry of an object. A (:,:,1) is a matrix corresponding to x coordinates …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.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.

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 …
