2.1.16.6.4.5 jacobian_theta

Description

Jacobian theta functions with real arguments

double jacobian_theta( int k, double x, double q )

k: [input] the function thetak(x,q) to be evaluated. Note: 0<=k<=4, k=4 is equavalent to k=0
x: [input] the argument x of the funtion
q: [input] the argument q of the funtion

Returns the values of one of the Jacobian theta funtions for a real argument x and non-negetive q<=1

EX1

void jacobian_theta_ex1()
{
	int k =2;
	double x =0.7, q =0.4;
	printf("%2ld	%4.1f	%4.1f:	%12.4e\n",k,x,q,jacobian_theta(k,x,q));
}
