Mapping two matrix elements

Hello, I have two nxm matrices A and B and want to create new nxm matrix C which elements are key:value pairs of A and B elements.
Example:
A = [1 2;
3 4];
B = [5 6;
7 8];
C = [{1: 5} {2: 6}
{3: 7} {4: 8}];

Can you rewrite your desired C result using valid matlab syntax. {1: ...} is not valid matlab syntax, so it's difficult to understand what result you want. {1, 5}, {[1, 5]}, {'1: 5'} would be valid syntax but it's not clear if it's any of these that you want.
Perhaps, you should explain what you're going to do with the result afterwards.

I want to create new matrix, which nth element is pair of A's nth element and B's nth element. For example, if A(1,3) = 5 and B(1, 3) = 42, C(1, 3) would be {5->42} (not the vector [5 42]).
I don't know how it works in MATLAB, but in python there is dictionary for this purpose.

I believe the closest MATLAB equivalent to python's dictionary is a map container.

Yes, matlab's map container and python's dictionary are both implementation of associative arrays.
However, the map in matlab, just like the python dictionary is an unordered container, so I'm confused for the requirement of the output being a 2D matrix, which implies some ordering.
