Now I want to go backwards, I did some editing to the image, and now I want to make it 3D again, with 144 dimensions. Reshape a 3D matrix. I want to reshape it in such a way that I extract two colums from each third dimension. Here, row_num and col_num are the number of rows and columns in the matrix .. "/>. B(:,:,4) = 7 3 You can then apply unique with the 'rows' option on this to get your labels. from which I create a meshgrid (I use this 3D mesh to compute some values so that I have also a 3D matrix A of size 3-by-3-by-3. 6 5 5 9, B(:,:,1) = 5 1 5 4 Based on 1 5 9 13 4 8 12 16 21 22 17 18 19 20 Unable to complete the action because of changes made to the page. I have a 3D matrix of 36*42*7 dimension. Yes, MATLAB does 'think' along rows. For example, reshape a 3-by-4 matrix to a 2-by-6 matrix. Any help is appreciated, thank you in advance. MathWorks is the leading developer of mathematical computing software for engineers and scientists. Learn more about 23, 2d, reshape 5 1 5 6 Start Hunting! Simpler code is less buggy (as the answers on this thread demonstrate). The example above, gave us the magic matrix (4) in the first line of code. How can it be done for large matrix of 36*42*7? Other MathWorks country Accelerating the pace of engineering and science. Based on I want to construct a three dimensional matrix that stores each k by m matrix in a different layer in the third dimension. I want to reshape it in such a way that I extract two colums from each third dimension. 5 3 Z1(:,:,2) = 21 22 23 24 Cambiar a Navegacin Principal For example, Assume I have 4*4*3 matrix Theme Copy A1= [a b c d; e f g h; i j k l; m n o p] A2= [q r s t; u v w x; y z A B; C D E F] Z3(:,:,3) = 33 34 35 36 Navigazione principale in modalit Toggle. Here is the original reshaping: [r c d] = size (data); % Originally a 340x740x144 array. Copy. 34 38 42 46 5 7 If one assumes that everything should be columnwise, then you can just use reshape().
