[scilab-Users] Problem in datafit

[Carrico, Paul]

Hi,

Thanks for this first answer ... However :

A) I noticed result differences between Excel and Scilab ... I can imagine that numbers are codded differently in Excel ! 
   I'll have a look in the help file to change the format numbers

B) By "how to empty memory" => I noticed that when I launch several times the same program, some parameters have been remaining in memory (and if I'm changing something in a debbug step, sometimes the mistake appears afterward i.e. after closing and re-opening Scilab)

=> so does it exist like "del memory" that I put on the top of the program ?

Regards

PC

The number of digits displayed for numbers, and the floating point or 
scientific format
-- that can be tuned thanks to the format() function -- has no effect on 
calculation accuracy.
Calculations are always done at full accuracy. The relative accuracy for 
scilab calculations
is %eps.
For engineering format : format("e"). See help format

I don't clearly understand what you mean. Variables can be erased
(and then memory is disallocated) with "clear". See help clear
For graphical objects, delete() must be used.
