Motzkin: Motzkin numbers

Description

Under OEIS A001006, a Motzkin number for a given n is the number of ways for drawing non-intersecting chords among n points on a circle, where the first 7 entries are 1, 1, 2, 4, 9, 21, 51.

Usage

Motzkin(n, Rmpfr = TRUE, PrecisionBits = 496)

Arguments

n

the number of first n entries from the sequence.

Rmpfr

a logical; TRUE to use large number representation, FALSE otherwise.

PrecisionBits

a positive integer for precision bits larger than 2.

Value

a vector of length n containing first entries from the sequence.

Examples

# NOT RUN {
## generate first 30 Motzkin numbers
first30 = Motzkin(30)

## print without trailing 0's.
print(first30, drop0trailing = TRUE)

# }
