elliptic (version 1.2-2)

p1.tau: Does the right thing when calling g2.fun() and g3.fun()

Description

Takes vectors and interprets them appropriately for input to g2.fun() and g3.fun(). Not really intended for the end user.

Usage

p1.tau(b)

Arguments

b

Vector of periods

Value

• Returns a two-component list:
• p1
  First period
• tau
  Period ratio

Details

If b is of length two, interpret the elements as $\omega_1$ and $\omega_2$ respectively.

If a two-column matrix, interpret the columns as $\omega_1$ and $\omega_2$ respectively.

Otherwise, interpret as a vector of $\tau=\omega_1/\omega_2$.

Examples

p1.tau(c(1+1i,1.1+23.123i))
