How to convert a multidimensional matrix into 2D ?

I have a 101x101x101 matrix. In order to plot it, I need to convert it to 2D. How can this be done ?

Hi Vladimir,

There are multiple options to do so.

Option 1: Use the "reshape" function

• You can change the matrix dimension by using the "reshape" function. Note that, "reshape" function reads elements of matrix columnwise first and then row-wise for reshaping it. For more information, you can check the documentation for "reshape".

Option 2: Write a simple code, as below, to stack matrices one after another.

NewA = zeros(101*101, 101); % A is original matrix.
% Here I am stacking 2-D matrices after one another with respect to the third
% dimension
for idx3 = 1 : 101
    NewA(1+((idx3-1)*101):(idx3*101),:) = A(:,:,idx3);
end
