+## Add data in 1D/2D CELL array @var{arr} into a cell range specified in
+## @var{range} in worksheet @var{wsh} in an Excel spreadsheet file
+## pointed to in structure @var{xls}.
+## Return argument @var{xls} equals supplied argument @var{xls} and is
+## updated by oct2xls.
+##
+## A subsequent call to xlsclose is needed to write the updated spreadsheet
+## to disk (and -if needed- close the Excel or Java invocation).
+##
+## @var{arr} can be any 1D or 2D array containing numerical or character
+## data (cellstr) except complex. Mixed numeric/text arrays can only be
+## cell arrays.
+##
+## @var{xls} must be a valid pointer struct created earlier by xlsopen.
+##
+## @var{wsh} can be a number or string (max. 31 chars).
+## In case of a yet non-existing Excel file, the first worksheet will be
+## used & named according to @var{wsh} - extra empty worksheets that Excel
+## creates by default are deleted.
+## In case of existing files, some checks are made for existing worksheet
+## names or numbers, or whether @var{wsh} refers to an existing sheet with
+## a type other than worksheet (e.g., chart).
+## When new worksheets are to be added to the Excel file, they are
+## inserted to the right of all existing worksheets. The pointer to the
+## "active" sheet (shown when Excel opens the file) remains untouched.
+##
+## If @var{range} is omitted or just the top left cell of the range is
+## specified, the actual range to be used is determined by the size of
+## @var{arr}. If nothing is specified for @var{range} the top left cell
+## is assumed to be 'A1'.
+##
+## Data are added to the worksheet, ignoring other data already present;
+## existing data in the range to be used will be overwritten.
+##
+## If @var{range} contains merged cells, only the elements of @var{arr}
+## corresponding to the top or left Excel cells of those merged cells
+## will be written, other array cells corresponding to that cell will be
+## ignored.
+##
+## Optional argument @var{options}, a structure, can be used to specify
+## various write modes.
+## Currently the only option field is "formulas_as_text", which -if set
+## to 1 or TRUE- specifies that formula strings (i.e., text strings
+## starting with "=" and ending in a ")" ) should be entered as litteral
+## text strings rather than as spreadsheet formulas (the latter is the
+## default).
+##
+## Beware that -if invoked- Excel invocations may be left running silently
+## in case of COM errors. Invoke xlsclose with proper pointer struct to
+## close them.
+## When using Java, note that large data array sizes elements may exhaust
+## the Java shared memory space for the default java memory settings.
+## For larger arrays, appropriate memory settings are needed in the file
+## java.opts; then the maximum array size for the Java-based spreadsheet
+## options may be in the order of 10^6 elements. In caso of UNO this
+## limit is not applicable and spreadsheets may be much larger.
+##
+## Examples:
+##
+## @example
+## [xlso, status] = xls2oct ('arr', xlsi, 'Third_sheet', 'AA31:AB278');

+## Created: 2009-12-01
+## Updates:
+## 2010-01-03 (OOXML support)
+## 2010-03-14 Updated help text section on java memory usage
+## 2010-07-27 Added formula writing support (based on patch by Benjamin Lindner)
+## 2010-08-01 Added check on input array size vs. spreadsheet capacity
+## '' Changed argument topleft into range (now compatible with ML); the
+## '' old argument version (just topleft cell) is still recognized, though
+## 2010-08014 Added char array conversion to 1x1 cell for character input arrays
+## 2010-08-16 Added check on presence of output argument. Made wsh = 1 default
+## 2010-08-17 Corrected texinfo ("topleft" => "range")
+## 2010-08-25 Improved help text (section on java memory usage)
+## 2010-11-12 Moved ptr struct check into main func. More input validity checks
+## 2010-11-13 Added check for 2-D input array
+## 2010-12-01 Better check on file pointer struct (ischar (xls.xtype))
+## 2011-03-29 OpenXLS support added. Works but saving to file (xlsclose) doesn't work yet
+## '' Bug fixes (stray variable c_arr, and wrong test for valid xls struct)
+## 2011-05-18 Experimental UNO support
+## 2011-09-08 Bug fix in range arg check; code cleanup
+## 2011-11-18 Fixed another bug in test for range parameter being character string

+## Updates:
+## 2009-12-11
+## 2010-01-12 Fixed skipping empty array values (now Excel-conformant => cell cleared)
+## Added xls.changed = 1 statement to signal successful write
+## 2010-07-27 Added formula writing support (based on POI patch by Benjamin Lindner)
+## Added check for valid file pointer struct
+## 2010-08-01 Improved try-catch for formulas to enter wrong formulas as text strings
+## 2010-08-01 Added range vs. array size vs. capacity checks
+## '' Code cleanup
+## '' Changed topleft arg into range arg (topleft version still recognized)
+## 2010-08-03 Moved range checks and cell type parsing to separate routines
+## 2010-08-11 Moved addcell() into try-catch as it is addCell which throws fatal errors
+## 2010-10-20 Improved logic for tracking file changes (xls.changed 2 or 3); dropped
+## '' internal variable 'changed'
+## 2010-10-27 File change tracking again refined
+## 2010-11-12 Moved ptr struct check into main func
+## 2012-01-26 Fixed "seealso" help string
+## 2012-02-27 Copyright strings updated
+## 2012-05-21 "Double" cast added when writing numeric values
+## 2012-05-21 "Double" cast moved into main func oct2xls
