Im new to MATLAB, still getting around the basic commands. Say you have the below, and I want to output the Matrix A or output the value of Q1. Or any other variable. Something like C++ cout of javas System.out.println functions.

%Krylov example

% state space
A=[-3 1 0 0;1 -3 1 0;0 1 -3 1; 0 0 1 -2];
B=[1;0;0;0];
C=[1 0 0 0];

% matching moments at infinity
Q1=B/norm(B);

If you omit the semicolon (;) from the end, the output will be on the screen. You can just type the variable name and hit Enter.

Another way is DISP function. Type disp(A) or disp(Q1).

For more sophisticated output you can use SPRINTF function:
disp(sprintf('Q1 value is %d\n', Q1))

For more information see SPRINTF doc:
