I'm struggling with the rows index of the matrix.
First I have Matrix A which is 1125 X 30 dimensions. I want to initialize Matrix B as 10 X 30, first as zeros and then matrix B takes the first ninth rows of matrix A, and keep its last rows as zeros. How can I do that?

Is this what you want?
B = zeros(10,30); % initialize Matrix B as 10 X 30, first as zeros
B(1:9,:) = A(1:9,:); % B takes the first ninth rows of matrix A
