MATLAB: How to create arrays for 3D matrix

matrixmatrix array

Hello

I created an array in order to put the results into it. Meanwhile, my matrix is 3D.

The 3D matrix is:

[4,3,2]=size(S)

And the created array is:

Result=[];

Is that a true definition?

Cheers

Best Answer

k = rand(4,3,2) ;  % create random 3d data 
[m,n,p] = size(k) ;  % get size

MATLAB: Is there an efficient way to create a 3 dimensional sparse matrix

A solution depends on what you want to do with the data:

All sparse methods I know are optimized for 2D array manipulations. Therefore I assume, that the creation of the 3D-sparse array will not be the bottleneck for the complete program. If you do not need optimized 2D matrix manipulation methods, you can store the data in a cell array of 2d sparse matrices also, or in one 2D sparse array using a conversion of the indices.

MATLAB: Extract 3D cells with nonzero elements, from a 3D cell array.

clc; clear all ;
load Mask.mat ;
k = Combinedmask ;
[m,n,p] = size(k) ;
count = 0 ;
for i = 1:p
    ki = k(:,:,i) ;
    if sum(any(ki))~=0
        count = count+1 ;
        iwant{count} = ki ;
    end
end
