I have a matrix of order nx2 (n is more than 3000)
I want to brake this matrix into multiple matrix of order 300x2 as well as name them eg: matrix1 = (1:299)x2 matrix2 = (300:500)x2 . . . matrix10 = (2700:2999)x2 and so on
can anyone know how to do this through script.

You are much better off using mat2cell() to create a single cell array
mat2cell(YourMatrix, 300 * ones(1,10), 2)

You may also consider converting it into a 3D matrix
iwant = reshape(yourmatrix,[300,2,3000/(300)]);
You can access the matrix by iwant(:,:,i) i = 1,2,...10

[m,n] = size(yourmatrix);
% k - number rows in new array(s)
% if rem(m,k) ~= 0
out1 = mat2cell(A,accumarray(ceil((1:m)/k)',1),n);
out2 = permute(reshape([A; nan(mod(-m,k),n)].',n,k,[]),[2 1 3]);
