having trouble with xlswrite

[Jasim Ahmed[jahmed]]

Hello there,

I am a new user of GNU Octave and want to use the xlswrite function. I tried the following example and got an error:

 

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

>> A = [1 5; 3 -0];

>> rstatus = xlswrite('test1.xls', 'A') ;

error: 'r_extnd' undefined near line 171 column 27

error: called from

    xlswrite at line 171 column 3

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

 

I also tried the example given in the help section of xlswrite and got a different error:

 

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

>> arr = [4 5; 1 3];

>> status = xlswrite('test4.xls', 'arr', 'Third_sheet', 'C3:AB40');

Detected XLS interfaces: warning:  No Java support found (no Java JRE? no Java pkg installed AND lo

aded?)

    xlswrite at line 202 column 9

 

None.

warning: xlsopen.m: no'.xls' spreadsheet I/O support with available interfaces.

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

 

Curiously enough xlsread seems to work (although there are some warnings):

 

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

>> [An, Tn, Ra, limits] = xlsread ('test5.xlsx', 'A1:B2');

Detected XLS interfaces: warning:  No Java support found (no Java JRE? no Java pkg installed AND lo

>> An

An =

 

   1   2

 

>> Tn

Tn =

{

  [1,1] = ash

  [1,2] = jas

 

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

I am using Octave 4.2.0 on a Windows 7 64 bit machine.

 

Can any one help me? Thanks,
