I have a matrix of size 10,000 x 4 or longer. When I display this matrix in the Command Window I only get to see perhaps the last few thousands rows of data and the Command Window wouldn't allow me to scroll further up to view the rest of the rows that come before that. My only way to get around it is to view the rows by range:

output(1:50,1:4)       % view the first 50 rows of all 4 columns
output(51:100,1:4)     % view the next 50 rows
output(101:150,1:4)    % so on and so forth ... for 200 times

Is there any build-in function or setting that help us to view or scroll through long matrix easier?

You can look at the matrices in the variables window. To do this:

create the matrix (e.g. bla = rand( 10000,4) )
double click on the variable in the workspace (in this example bla)
this wil open the variables menu, here you can scroll trough the complete matrix
