Maxima 5.31 change log Changes in core: * Galois fields: revision, introduction of extension fields * inverse_jacobi_sn: improve accuracy * Bessel functions: integral of bessel_i, bessel_j of arbitrary order * matrix functions: revise ModeMatrix, mat_function, dispJordan, diag, JF * signum: do not declare signum real- or integer-valued * carg: declare carg real-valued * parser: add L, l, W, and w to list of exponent marker characters Changes in share: * package stringproc: new functions readchar, md5sum, base64 Other changes: * documentation: minor changes to make Texinfo 5 happy * build system: changes to make Maxima build correctly on Windows Bug fixes: * 2622 base64 type warnings * 2619 Function inverse_erf - error in numerical evaluation * 2612 known_units() broken * 2608 quad_qags(x,x) generates a lisp error * 2607 lbfgs documentation is incomplete * 2604 fft.dem is out of date * 2603 fft documentation * 2602 lu_factor regression * 2599 cl-info error handling * 2597 logcontract and subscripted log * 2594 Incorrect integration of product of cosines * 2591 risch gives Lisp error for sinh expression * 2583 sign error for integrate(x^(8*%i-1),x); * 2570 Make acos(cos(x)) simplify to x when on correct interval * 2569 translate rat(1,x) and rat([1]) incorrect * 2536 Lisp error in limit: \ * 2501 %pi/8 is definitely not an integer * 2475 limit(x^(mu/x^g),x,inf) --> error unnumbered bugs: * mailing list 2013-05-22: "array-lambda error with 5.30.0" * mailing list 2013-05-07: "defrule regression compare to version 5.29.1" * fix rk() when the independent variable's initial value is nonzero * fix bug in asksign * fix wrong noun form returned for jacobi_nc(elliptic_kc(m)/n,m)
