Concatenate arrays in MATLAB and Change Column name of Table

I am trying to concatenate a cell array and a double but can't achieve that. Cell array can be generated using below code.

test = {'A.X'  'B.Y' 'C.Z'} ;

Double array can be generated using below code.

test_double = [10 20 30; 40 50 60];

I tried concatenating them using following code

cat(1, test, test_double)

But I get dimension error as follows

Dimensions of matrices being concatenated are not consistent.

Also if I convert the double array to table and rename the columns using input form cell array it gives me an error

'A.X' is not a valid variable name.

Above error can be replicated using following code

test_table = table(test_double);
test_table.Properties.VariableNames = test; 

How can I concat the arrays?

How can I convert double array to table and rename columns using cell array?

t = [10 20 30; 40 50 60];
A = t(:,1) ; B = t(:,2) ; C = t(:,3) ;
T = table(A,B,C)

Provide solution does not takes into acccount the naming of column for table as asked. Also this is just a dummy example there might be more than 100 columns therefore the following code is not an efficient way to achieve the results.

A = t(:,1) ; B = t(:,2) ; C = t(:,3) ;

You cannot use A.x as variable name. You can use arrayu2table.

T = array2table(A) ; % A is your matrix

[Furqan Hashim]

If variables can't be named as suggested can below 2 arrays be concatenated?

test = {'A.X'  'B.Y' 'C.Z'} ;
test_double = [10 20 30; 40 50 60];

As of release R2019b table variable names are not required to be MATLAB identifiers.

test = {'A.X'  'B.Y' 'C.Z'} ;
test_double = [10 20 30; 40 50 60];
T = array2table(test_double, 'VariableNames', test)

T = 2x3 table
    A.X    B.Y    C.Z
    ___    ___    ___

    10     20     30 
    40     50     60 

It does require slightly different syntax to access the variables by name using dot notation if the names aren't MATLAB identifiers.

% T.A.X would not work
x = T.('A.X')

x = 2×1

10 40

Indexing using parentheses or curly braces works, though.

z2 = T{2, 'C.Z'}

z2 = 60
