EN is a library function for computing Euler numbers and polynomials. The EULER NUMBERS command can be used to generate a sequence of Euler numbers.
The Euler numbers overflow quickly. For single precision Dataplot, the overflow typically starts occurring at N=40. This may vary slightly depending on the platform.
where <start> is the starting row for the Euler numbers;
<inc> is the increment for the Euler numbers;
<stop> is the stopping row for the Euler numbers;
<y> is a variable where the Euler numbers are saved.
Typically <start> and <inc> are 1 and <stop> is set to the number of Euler numbers to generate. If <start> and <inc> are not 1, then <y> will still contain <stop> elements, but the empty rows will be set to 0.
Dataplot generated the following output:
