Accessing data in matrix entries of tables

Dear all,

I am having trouble to access matrix data in tables. To explain better my problem I'm posting a MWE.

x = {1 "abc" [1 2;2 1];2 "def" [3 4;4 3];3 "ghi" [3 4;4 3]};
T = cell2table(x,'VariableNames',{'id','names','matdata'});

I am able to access data in table T as rows and variables. For example I can access the 1st row of "id" variable as:

T{1,'id'}

I am not able to access the table first row of variable "matdata" as a double matrix directly (the operation below returns a cell):

T{1,'matdata'}

So, my question is if there is a direct way to access the matrix [1 2;2 1] as a double, and if possible to access even directly to its rows or columns with a sigle line of code, so without the need of an auxiliary variable. By now I found this solution but it needs an auxiliary variable:

aux = table2array(T{1,'matdata'});
aux(1,:)

Instead I can do this directly with the "x" cell:

x{1,end}(1,:)

Thanks to all in advance for your advice and suggestions!

You can use multiple sets of curly braces {} to index into cells, and then use parentheses to index into the resulting arrays, like this:

>> T{1,'matdata'}{1}(1,:)

ans =

1 2

Thank you very much for your answer!
