Take a minute and describe your problem. Your description is nowhere close to your post's title.

plz ans....

Answer 1

[Birdman]

x=[1 2 3 4;6 7 3 4];
y=['A' 'B' 'C' 'D'];
x=reshape(char(string(x(:))),2,4);
Table=array2table([x;y])

[Nixon Dhar]

I mean x= 1 2 3 4

Y= A B C D

REQUIRED

1 2 3 4

A B C D

[Birdman]

x=[1 2 3 4];
y=['A' 'B' 'C' 'D'];
x=reshape(char(string(x(:))),1,4);
Table=array2table([x;y])

T1  = array2table([1,2,3,4; 5,6,7,8]);
T2  = array2table('ABCD')
C12 = [table2cell(T1); table2cell(T2)];
T12 = array2table(C12)

Mh, I'm not convinced. There should be a way without a conversion to a cell. But:

T12 = [T1; T2]

sets the values of the numbers to empty matrices.

[Nixon Dhar]

it works well,real.size s 4356*400,bt when I want to see the table,it taking too much time,why??

[Jan]

What exactly is "too much"? You can use the profiler to find out, where the time is spent.

[Peter Perkins]

The problem here is that the requirement of two rows that are numbers and one row that is text is exactly the opposite orientation that tables are designed for. So Jan's solution creates what is essentially one 3x4 cell array, with numbers in some cells and text in others, while cvklpstunc's solution turns the numbers into text.

I'm guessing that this is all about display, not about creating a table for manipulating data. If you were storing those data, you'd want to do it like this:

>> x = [1 2 3 4;6 7 3 4];
>> y = ['A' 'B' 'C' 'D'];
>> t = table(x(1,:)', x(2,:)', y')
t =
  4×3 table
    Var1    Var2    Var3
    ____    ____    ____
     1       6       A  
     2       7       B  
     3       3       C  
     4       4       D

Jan's solution ends up displaying something like

T12 =
  3×4 table
    C121    C122    C123    C124
    ____    ____    ____    ____
    [1]     [2]     [3]     [4] 
    [5]     [6]     [7]     [8] 
    'A'     'B'     'C'     'D'

which probably is not desirable for display.
