%Lets twst a few simple operations;

    %row vector
    x=[10 2 5 8];

    %column vector
    y=[6.3; 3.2; 8.1; 1.2];

    %another row vector
    z=[12.3, 3.4, 6.78, 9.01];
    
    %matrix
    A=[1 0 0 1;
       0 -1 8 4;
       3 0 0 0;
       0 0 0 2];
  
    %another matrix
    B=[ 1, 3, 5 ,6; 2, 4, 6, 7; 6, 4, 2, 9; 1, 0, 0, 1];
    
    %one more
    C=[1, 0, 0, 0;
        0, 1, 0,0;
        0, 0, 1, 0;
        0, 0, 0, 1];
    
    %do some operations
    a=x+z
    b=3*y
    c=sin(x)
    
    %some others with transpose
    d=x'+y
    e=d+z'
    f=4*d+2*e
    
    %some matrix operations
    g=A*y
    h=B*z'
