Maxima 5.13.0 change log Compiled 2007-08-04 Backwards-incompatible changes: * unstore, fassave, restore: cut out undocumented functions New items in core: * unique: function to return unique elements of a list * New function float_approx_equal w/ associated global variable float_approx_equal_tolerance (for test suite cases) * Interface to Lisp string streams: make_string_input_stream, make_string_output_stream, get_output_stream_string New items in share: * vector3d package (thanks to Walter Eastes) * Script share/share_testsuite.mac to run tests in share * share/contrib/topoly.lisp: new functions elim and elim_allbut New items in tests: * Commit test scripts written by Michael Wester Other revisions: * run_testsuite: only simplify expected results, do not evaluate, and do not call ratsimp; now tests are more stringent than before * equal: recognize Maxima and Lisp arrays and Maxima and Lisp strings * find_root: evaluate arguments in an ordinary way * apply, outermap: evaluate arguments in an ordinary way * save, loadfile, tex, stringout, compfile: evaluate filename argument * display code: output space characters (no tabs) * share/linearalgebra: improved jacobian and hessian functions * share/contrib/lsquares.mac: replaced with a new version * share/draw: include geographical data from World Boundaries Database; other modifications * with_stdout: accepts an output stream as well as a filename * share/contrib/topoly.lisp: many improvements in to_poly * share/contrib/numericalio: accept stream as well as a filename * many other minor improvements Bug fixes not otherwise mentioned: * 1754072: $piargs bug * 1751951: diag_matrix() with block matrices gets off-diag boxes wrong * 1748168: integrate(1/(2+cos(x)),x,-%pi/2,%pi/2); wrong * 1741705: integrate(1/(sin(x)^2+1),x,0,8) wrong * 1732315: trigrat dies on a matrix * 1732298: postscript eps file error * 1730044: powerseries(1+x^n,x,0) wrong * 1729642: conjugate error * 1729432: onep1 / FIX * 1726002: bug in coerce-float-fun * 1722156: powerseries((x+1)/(1-2*x^2), x, 0); * 1721027: trigrat(sin('x)) captures x * 1714044: Maxima asks unnecessary questions in integration * 1690374: asin(1 / sqrt(2)) * 1562340: trigrat doesn't distribute over = * 1552789: integrate(1/(sin(x)^2+1),x,1,1+%pi) takes forever * 1490397: subres gcd wrong
