Hi,

i want to generate some random numbers that have poisson distribution.
i found this labtalk command:
Poisson(npts, mean, seed)

Does anybody know how can i use this command to generate a random number?

I tried this:

void test()
{
col(1)=Poisson(10, 0, 2);
}

but this is not working.

Thanks in advance

Maybe you got the parameters wrong?

For me, this works:

col(1)=poisson(10,3);

or col(1)=poisson(10,3,2);

Just using what you used, col(1)=poisson(10,0,2); just gave me zeros in col(1).

Here is how you can use the LabTalk function Poisson,

 

void tt(int nCol = 1)
{
	LT_execute("temp=Poisson(1000, 3)");// create 1000 points with mean = 3, result in dataset called temp
	Worksheet wks = Project.ActiveLayer();
	Dataset dtemp("temp");// dataset temp can be accessed in OC like this
	Dataset aa(wks,nCol-1);// col(1), col(2) etc as Dataset
	aa = dtemp;
	LT_execute("del temp");// best to clean up temp dataset
}





Or you can also call the nag_poisson_dist function, which is more involved.
