function t = array2table(x,varargin) %#codegen

%ARRAY2TABLE Convert homogeneous array to table.

%   T = ARRAY2TABLE(A) converts the M-by-N array A to an M-by-N table T.

%   Each column of A becomes a variable in T.

%

%   NOTE:  A can be any type of array, including a cell array.  However, in that

%   case you probably want to use CELL2TABLE instead.  ARRAY2TABLE creates the

%   variables in T from each column of A.  If A is a cell array, ARRAY2TABLE

%   does not extract the contents of its cells -- T in this case is a table each

%   of whose variables is a column of cells.  To create a table from the

%   contents of the cells in A, use CELL2TABLE(A).

%

%   T = ARRAY2TABLE(X, 'PARAM1', VAL1, 'PARAM2', VAL2, ...) specifies optional

%   parameter name/value pairs that determine how the data in X are converted.

%

%      'VariableNames'  A string array or cell array of character vectors

%                       containing variable names for T.  The names must be

%                       valid MATLAB identifiers, and must be unique.

%      'RowNames'       A string array or cell array of character vectors

%                       containing row names for T.  The names need not be

%                       valid MATLAB identifiers, but must be unique.
