Put name on above and left

How can I put the name on above and left side of the matrix?

For example, I have a matrix but there are only numbers (In fact I have more than 100 numbers)

1   5   4   8  
1   2   4   8  
5   8   9   2  
2   6   3   4

If I want to put A, B, C, D, and E on the head and X, Y, Z and N on the left, how can I do that through the code?

It should be:

A   B   C   D   E
X   1   5   4   8  
Y   1   2   4   8  
Z   5   8   9   2  
N   2   6   3   4

All elements in an array must be of the same type, i.e. you cannot merge numbers with characters unless you turn the numbers into characters too.

You could do this

A = rand(4,5);
header = ["B" "C" "D" "E" "F"];
fields = ["A" "X" "Y" "Z" "N"];
A = [fields',[header;A]]

Alternatively, take a look at table.

Thank you for you reply!

However, I have more than 100 numbers. So, do I need to type alphabets 100 times? or is there another way through the code?

What header will you use after you run out of alphabet letters?

This is close to what you can do with a table. However, since you only have four columns in your data array, I don't understand why you want labels A through E across the top as column labels (or what is referred to as the VariableNames of a table).

See if this is what you actually want:

A = [1   5   4   8
     1   2   4   8
     5   8   9   2
     2   6   3   4];
array2table(A, 'RowNames', {'X', 'Y', 'Z', 'N'}, 'VariableNames', {'A', 'B', 'C', 'D'})

ans = 4×4 table
         A    B    C    D
         _    _    _    _

    X    1    5    4    8
    Y    1    2    4    8
    Z    5    8    9    2
    N    2    6    3    4
