I have a 1-D array (1*11). I need to make it a 4D matrix (11*11*11*11). The number of data (11) for each dimension are the same. For example, the 1-D array is A=0:1:10. This A needs to be turned into 4-D matrix. How can I do that? How to write the code for that?

I understand that you wish to obtain a 4-D Matrix from a 1-D Matrix of 11 data elements.
Taking the example of A=0:1:10, we can obtain the 11 x 11 x 11 x 11 matrix using 'ndgrid' function.
Here's how you can achieve it:
A = 0:1:10;
% Use 'ndgrid' to expand A into 4D
[B1, B2, B3, B4] = ndgrid(A, A, A, A);
% These 4 B1, B2, B3, B4 can be combined in any desired way to obtain
% desired result.
% For Example:
B = B1 + B2 + B3 + B4;
You can refer to the following MATLAB documentations to know more about these functions:
Hope this helps! Thanks.
