function datasetout = importindex(workbookFile,sheetName,startRow,endRow)
%IMPORTFILE Import data from a spreadsheet
%   DATA = IMPORTFILE(FILE) reads data from the first worksheet in the
%   Microsoft Excel spreadsheet file named FILE and returns the data as a
%   dataset array.
%
%   DATA = IMPORTFILE(FILE,SHEET) reads from the specified worksheet.
%
%   DATA = IMPORTFILE(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.
%
%	Date formatted cells are converted to MATLAB serial date number format
%	(datenum).
%   Non-numeric cells are replaced with: NaN
%
% Example:
%   Index = importfile('index.xlsx','Sheet1',2,13);
%
%   See also XLSREAD.
