How to extend the matrix size by splitting up a column in two columns

There is a Matrix A, which can have variable size, for example (5x4):

 A = 
|10  2     0.0  6|
|10  2    18.0  6| 
|10  2  1800.0  6|
|10  2  1810.0  6|
|10  2  2215.0  6|

Now there's a specific column (3rd column), which I wish to be separated in two different columns, but next to each other, like this:

 A = 
|10  2   0   0  6|
|10  2   0  18  6| 
|10  2  18  00  6|
|10  2  18  10  6|
|10  2  22  15  6|

Such a column can also appear in the first or last column. Then it is separated in the same way. The matrix size then gets (5x5) in this case.

The numbers in the specific column are always non-negative integers and can only contain numbers between 0000 - 9999. the first two digits belong to the one column, the next two digits belong to the next column.

 A= [10  2     0.0  6;...
 10  2    18.0  6;... 
 10  2  1800.0  6;...
 10  2  1810.0  6;...
 10  2  2215.0  6];

 Str = mat2cell(reshape(sprintf('%04i',A(:,3)),4,[])',ones(size(A,1),1),[2 2]);
 your_vals = cellfun(@(x) str2double(x),Str);
 A(:,3) = [];
 A = [A(:,1:2) your_vals A(:,3:end)];

Wow, impressing! Thank you!

[Jos (10584)]

A = [1 1 1800 1 ; 2 2 1815 2 ; 3 3 6512 3]

C = A(:,3)
c2 = rem(C,100)
c1 = (C - c2)/100
output = [A(:,[1 2]) c1 c2 A(:,4)]

Your solution is even more simple! Thanks!
