I am trying to convert a cell array to string. Got stuck in this.

[num_data,headers]=xlsread(Excel_file_name,Worksheet_name,range_select);
len_headers=max(size(headers));
for var=1:len_headers
  var
  dummy=headers(var)
  eval(strcat(dummy,'=genvarname(headers{var});'));
  eval(strcat(dummy,' = num_data(:,var);'));
end

Variable definitions:

But this is giving an error as eval() accepts only strings. dummy remains a 1x1 cell array and after using strcat, the final output of strcat also remains a cell array.

The problem is of converting a cell array to a pure string.

Avoid eval(). There is a nicer, faster and more reliable method always.

[num_data, headers] = xlsread(Excel_file_name,Worksheet_name,range_select);
len_headers = length(headers);   % Not MAX(SIZE())
for ivar = 1:len_headers              % Do not shadow builtin function VAR
      name = genvarname(headers{ivar});
      Data.(name) = num_data(:,var);
end
