Continue in a for loop if a file isn't present

I'm having a problem with the correct syntax to complete the task without receiving an error. Any help is most appreciated!

In my program there is a for loop to import a series of spreadsheets into Matlab. These spreadsheets are for every US baseball team.

I want to know the syntax of how to skip and continue the for loop if one of the files within the loop are not found in the folder.

Here is the code i have so far:

for Str = {'Diamondbacks' 'Braves' 'Orioles' 'Boston' 'Cubs' 'WhiteSox' 'Reds' 'Indians' 'Rockies' 'Tigers' 'Astros' 'Royals' 'Angels' 'Dodgers' 'Marlins' 'Brewers' 'Twins' 'Mets' 'Yankees' 'Athletics' 'Phillies' 'Pirates' 'Padres' 'Giants' 'Mariners' 'Cardinals' 'Rays' 'Rangers' 'BlueJays' 'Nationals'};

folder = '';
   fileToRead1 = [Str{1} '.xls'];
   sheetName='Sheet1';

 // this is to organize the data in a way easy for me to use 

     [numbers, strings, raw] = xlsread(fileToRead1, sheetName);
  if ~isempty(numbers)
      newData1.data =  numbers;
  end

if ~isempty(strings) && ~isempty(numbers)
    [strRows, strCols] = size(strings);
    [numRows, numCols] = size(numbers);
    likelyRow = size(raw,1) - numRows;
    % Break the data up into a new structure with one field per column.
    if strCols == numCols && likelyRow > 0 && strRows >= likelyRow
        newData1.colheaders = strings(likelyRow, :);
    end
// Here is my feeble attempt to skip and continue the forloop if a file is
// not found.  It doesn't work of course.  
if ~isempty(fileToRead1)
    newData1.data =  numbers;
continue  
end
end

Continue if the file is not there:

if exist(fileToRead1, 'file') == 0
  % File does not exist
  % Skip to bottom of loop and continue with the loop
  continue;
end

I still am getting an error.

??? Undefined function or method 'exists' for input
arguments of type 'char'.

Error in ==> baseball4Test at 26
if exists(fileToRead1, 'file') == 0

I don't know what is going wrong.

I also tried:

if exists(fileToRead1, [Str{1} '.xls']) == 0
  % File does not exist
  % Skip to bottom of loop and continue with the loop
  continue;
end

And got the same error. Not sure what I'm doing wrong.

Use exist() instead of exists().

I make that mistake a lot myself!
