Xlswrite(FileName,DataArray,SheetName,CellRange) Writing data to Excel documents is also quite simple. To load such data, simply set the range of cells to be much larger than the existing range: xlsread will ignore the extra empty spreadsheet cells. Think of daily rainfall data stored in a single column within a spreadsheet, which periodically has data appended to it. Often, I find myself needing to read data from growing ranges of cells within Excel spreadsheets. where NumericData and TextData contain the numeric and text data read from the workbook, respectively and FileName, SheetName and CellRange are the names of the Excel document, sheet name and cell range from which to read. MATLAB's function for extracting data from Excel documents is xlsread. There is just one catch: For users without Excel to act as a COM server (such as UNIX users), 'basic' mode is required, and functionality will be limited: See help xlsread for details. The mechanics of this are not difficult, but I thought that readers might not be aware that this facility exists and just how easy this is to accomplish. Happily, MATLAB can easily get data from or send data to Excel documents. As I have a number of these reports to produce, I was motivated to construct a more automatic solution. Nearly everyone who produces such reports where I work does so by generating tables of numbers and cutting-and-pasting them into Excel (yuck!). Currently, such reports are distributed as Excel workbooks. Recently, I needed to assemble a report which is to be generated quarterly and distributed to those unfortunate enough not to have MATLAB.
