I have a matrix of 2*2=4 elements.Let it be x= [2 3 ; 4 5] i want separate the matrix into 2 matrixes. one matrix contains values should be less or equals to 2 and other matrix should contain values more than 2, and again i want to merge them back. Can anybody suggest how to do? Thank you.

@aditya sahu: what do you mean by "one matrix is less than 2": that the values should be less than two, or the number of elements should be less than two, or that it would contain the first two elements? I note that none of the elements has a value less than two.

Try this:
x= [2 3 ; 4 5]
mask = x <= 2;
x2 = x .* mask
x3 = x .* ~mask % Multiply by the inverse of the mask.
x4 = x2 + x3 % Combine together.
