gives the theta function .
- Mathematical function, suitable for both symbolic and numerical manipulation.
- The are defined only inside the unit q disk; the disk forms a natural boundary of analyticity.
- Inside the unit q disk, and have branch cuts from to .
- For certain special arguments, EllipticTheta automatically evaluates to exact values.
- EllipticTheta can be evaluated to arbitrary numerical precision.
- EllipticTheta automatically threads over lists.
