%importSummaryFile Import data from a spreadsheet
%   DATA = importSummaryFile(FILE) reads data from the first worksheet in the
%   Microsoft Excel spreadsheet file named FILE and returns the data as a
%   table.
%
%   DATA = importSummaryFile(FILE,SHEET) reads from the specified worksheet.
%
%   DATA = importSummaryFile(FILE,SHEET,STARTROW,ENDROW) reads from the specified
%   worksheet for the specified row interval(s). Specify STARTROW and
%   ENDROW as a pair of scalars or vectors of matching size for
%   dis-contiguous row intervals. To read to the end of the file specify an
%   ENDROW of inf.
%
%	Non-numeric cells are replaced with: NaN
%
% Example:
%   SubImageS2 = importSummaryFile('SubImage.xlsx','GoogLe13',2,5185);
%
