Hi everyone.

I have a 243938x1 Data matrix, and what I want to do is that I want to take the first 100 data (rows) of this matrix and put it in the first column of a defined Matrix Y.

then take the second 100 data (101-200) and put it in the second column of Y, and so on, till the Y Matrix is a 100x200 matrix.

can anyone help me with that? thanks .

在 MATLAB Online 中打开

data = rand(243938,1); % generate test data
n = 2; % Columns in Y
Y = nan(100,n); % initiate Y
% method 1, using forloop
for i = 1:n
	Y(1:100,i) = data( (1 + 100*(i-1)):(100*i));
	
end
% method 2, using reshape command
Y1 = reshape(data(1:(n*100)),[100,n]);
