If range is larger than the size of M, Excel fills the remainder of the region with #N/A. The size defined by range should fit the size of M or contain only the first cell, (e.g., 'A2'). (See help in Excel for more information on this notation.) The range input is not case sensitive and uses Excel A1 notation. The range 'D2:H4' represents the 3-by-5 rectangular region between the two corners D2 and H4 on the worksheet. Two cell designations separated by a colon, such as 'D2:H4', to indicate two opposing corners of the region to receive the matrix data.A cell designation, such as 'D2', to indicate the upper left corner of the region to receive the matrix data.Specify range using one of the following quoted string formats: Writes matrix M to a rectangular region specified by range in the first worksheet of the file filename. In either case, MATLAB generates a warning indicating that it has added a new worksheet. If sheet is an index larger than the number of worksheets, empty sheets are appended until the number of worksheets in the workbook equals sheet. If sheet does not exist, a new sheet is added at the end of the worksheet collection. The sheet argument can be either a positive, double scalar value representing the worksheet index, or a quoted string containing the sheet name.

Writes matrix M to the specified worksheet sheet in the file filename. The matrix data is written to the first worksheet in the file, starting at cell A1. The input matrix M is an m-by- n numeric, character, or cell array, where m < 65536 and n < 256. Writes matrix M to the Excel file filename. Write Microsoft Excel spreadsheet file (.
