Syntax

c = ellipke(x)

c = ellipke(x, tol)

[c, d] = ellipke(x)

[c, d] = ellipke(x, tol)

Description

Computes the complete elliptic integral of the first and second kinds.

Examples

Inputs

Name	Description
x	Specifies the elliptic modulus. x is a real scalar, vector, or matrix with values between 0 and 1.
tol	Specifies the approximation tolerance. tol is a positive real number. The default is eps.

Outputs

Name	Description
c	Returns the complete elliptic integral of the first kind. c is a matrix of the same size as x.
d	Returns the complete elliptic integral of the second kind. d is a matrix of the same size as x.

Examples

X = 0:0.01:0.9;
[C, D] = ellipke(X);
plot(X, C)
