Fw: memory exhausted error

[Ákos Gáborjáni Szabó]

 

Hi there -

 

I may have found a bug. - If you think it is not a real bug, and you have any idea how to solve it, please help me.

(I am using Octava for some statistical calculations to include them to my thesis. Since I am in a hurry because of the deadlines :) , I would really appreciate any help!)

 

I've running version 2.1.31 on windows 98 and windows 2000. Free RAM is more than 160M, free HDD is more than 100M in both of them.

On both systems Octave crashes when running a (quite simple) function file.

 

 

 

octave:1> C=korr_matrix("eq_stand.ocd",805,16,1,805)
Error: memory exhausted -- trying to return to prompt

 

D:\PROGRAM FILES\GNU\OCTAVE\USR\LOCAL\BIN\OCTAVE.EXE: *** MEM_COMMIT failed, Win32 error 8

The function file korr_matrix is:

 

function C=korr_matrix(filename,row,column,r_start,r_end)

## Calculate correl matrix of selected rows (r_start,r_end) in a matrix (row x column) from file filename, 
 [fid,msg]=fopen(filename,"r","ieee-le")
 ## column,row are replaced, because of the inverse format of the input file

 E=fscanf(fid,"%f",[column,row]) 
 fclose(fid)
 E=rot90(flipud(E),-1)
 E=E(r_start:r_end,:)
  m=mean(E)
 v=sum(tril(triu(sqrt(cov(E)))))
 [sor,oszlop]=size(E) 
 for i= 1:sor
  E(i,:)=(E(i,:)-m)./v
 endfor 
 C=corrcoef(E)
endfunction

 

------------------------------------------------------------------------------------------------------------------------

The data file eq_stand.ocd is a matrix with 805 rows, 16 columns, containing fixed floating point variables, separated with spaces. Data file format: first row first.

Thank you very much
