matrix = cat (2 ,[0; 6; 2; 4] , cat (1 ,[4 5; 6 7] ,[9 10; 11 12])); disp ( matrix ) in matlab

To create the matrix, you can use the cat function to concatenate arrays along specified dimensions. In this case, you can concatenate arrays vertically using the 2 as the dimension argument for the first cat function, and concatenate 2D matrices horizontally using 1 as the dimension argument for the second cat function.

Here's the code to create and display the matrix in MATLAB:

main.m
matrix = cat(2, [0; 6; 2; 4], cat(1, [4 5; 6 7], [9 10; 11 12]));
disp(matrix);
80 chars
3 lines

This will output:

main.m
     0     4     5
     6     6     7
     2     9    10
     4    11    12
76 chars
5 lines

Hope this helps!
