Origin Version (Select Help-->About Origin): 7.5SR4
Operating System:Win XP

Hi All,

I am fitting some curves using NLSF in Origin C.
In fitting the data im using error bars as an arbitrary dataset, so i have to supply a dataset which contain the error bars. for example:

Worksheet wks;
wks.Create();
Dataset Err(wks,0);
and then use :
NLSF.W$ = Err.GetName();

but i want to use instead of a dataset a vector, i.e :

double Err[100];
NLSF.W$ = Err.GetName();

because i dont want to create a dataset.
but if i do so im getting an error massage that says:Member's access requires struct/class type.

what shall i do?
Thanks a lot.
Pegor

Hi Pegor,

According to nlsf documentation nlsf.w$ must refer to an existing wks column. However, you can use a temporary wks (will be destroyed automatically on completion) like this...

Worksheet wks;
wks.Create("Origin.otw", CREATE_TEMP);
Dataset Err(wks,0);
and then use :
NLSF.W$ = Err.GetName();
