A = randi(100, 1, 19)
splits = [7 5];
B = mat2cell(A, 1, [splits, numel(A) - sum(splits)]);
celldisp(B)
Use cell arrays rather than numbered variables.

I'm not sure what you want me to elaborate on. You just pass the length of the submatrices you want the main matrix to be divided into, to mat2cell.

One way:
A = rand(1,19);
B1 = A(1:7);
B2 = A(8:12);
B3 = A(13:end);
