is editvar very slow ?

[davidcheze]

Hi,

 

I would like to know why editvar so slow is to edit quite large matrix
(5500 x 35) of double ? Same operation in Excel requires only a couple
of seconds while editvar is still working after 2-3 minutes.

 

-->M=csv_read('mesures_20101104.txt',ascii(9),'.')

M  =

 

 

         column  1 to 13

 

    Nan          Nan     Nan          Nan          Nan     Nan
Nan          Nan      Nan          Nan          Nan   Nan          Nan


    40486.472    1.16    53.845875    59.783516    0.82    57.828438
50.027088    0.62     52.962467    48.013382    0.    18.751423
18.507408  

-->size(M)

ans  =

 

    5500.    35.  

 

-->editvar M

 

Thanks for any piece of explanation

 

David
