Replacing element in table

I have this table

X1=[9 6 9;3 2 7];
X2=[0 2;4 0];
X3=[3 1; 8 9];

X=table(X1,X2,X3)

X = 2×3 table
        X1           X2        X3  
    ___________    ______    ______

    9    6    9    0    2    3    1
    3    2    7    4    0    8    9

How do I replace X3 with X1 so that i get

X1=[9 6 9;3 2 7];
X2=[0 2;4 0];
X3=X1;

X=table(X1,X2,X3)

X = 2×3 table
        X1           X2          X3     
    ___________    ______    ___________

    9    6    9    0    2    9    6    9
    3    2    7    4    0    3    2    7

Without having to make an new table that is.

You can do point to table variables with the syntax tablename.variablename:

X1=[9 6 9;3 2 7];
X2=[0 2;4 0];
X3=[3 1; 8 9];
X=table(X1,X2,X3)

X = 2×3 table
        X1           X2        X3  
    ___________    ______    ______

    9    6    9    0    2    3    1
    3    2    7    4    0    8    9

X.X3=X1 % or X.X3=X.X1 in this case

X = 2×3 table
        X1           X2          X3     
    ___________    ______    ___________

    9    6    9    0    2    9    6    9
    3    2    7    4    0    3    2    7
