Sorting a matrix elementwise is a strange job. If you do not consider the rows or columns, why is the input and output a matrix and not a vector? Please confirm that this does exactly what you want with Matlab commands:
a = [1 3 0;5 2 8;4 7 10]
b = reshape(sort(a(:)), size(a))
"No existing Matlab functions" cannot work. Even "=" calls subasgn and ">" calls the gt function. Without built-in functions, there is almost nothing, what can be done in Matlab at all.

Use this commands where a is input matrix and S_a is the your required answer.
a = [1 3 0;5 2 8;4 7 10]
b=sort(a(:));
S_a=vec2mat(b,3);

The question specifically mentioned not to use built-in sort() function.
