I need to call some columns of a table in automated way. The name pof table is T and I use this line to make the T.table_column:
variable_names=strcat('T.',var(i));
and the output of this code is:
variable_names =
1×1 cell array
{'T.i_nPix'}
I need to call T.i_nPix in which T is table name and i_nPix is table column. But this format {'T.i_nPix'} which is cell array and string is not able to be recognized as table.table_column. How can I solve the issue?

"Do you mean I should change the code lik this? strcat('T.(',var(i),')')"
No, that would be entirely the wrong way to go about this. Much simpler and more efficient to follow Walter Roberson's advice... which is the same as the MATLAB documentation:
