The JACOBIAN statement defines the JACOBIAN matrix J for a system of objective functions. For more information, see the section "Derivatives". proc nlp tech=levmar; array j[2,2] j1-j4; lsq f1 f2; ...

Using Jacobian elliptic functions we construct families of complete immersed minimal surfaces, with one, two or three ends and a non-trivial symmetry group. Journal Information This monthly journal, ...

IN the preface to his "Elliptic Functions", written in 1892, Prof. A. G. Greenhill complained that, although the subject was then nearly seventy years old, it had not made its way into the ordinary ...

An explicit addition formula is derived for the inverse sine-amplitude function. This is used to obtain an explicit formula for the inverse sine-amplitude function with complex argument. Journal ...
