1/72006年全国研究生数学建模赛试题B题确定高精度参数问题通过对此生态系统的观测，可以得到相关的观测数据。观测数据的格式依次为：观测时刻、A生物数目、B生物数目二：请利用有关数据，解决以下问题：1)在观测数据无误差的情况下，若已知，求其它5个参数？有关数据见数据文件：DATA1.TXT2)在观测数据无误差的情况下，若也未知，问至少需要多少组观测数据，才能确定参数？有关数据见数据文件：DATA1.TXT3)在观测资料有误差（时间变量不含有误差）的情况下，请分别利用观测数据DATA2.TXT和DATA3.TXT，确定参数在某种意义下的最优解，并与仿真结果比较，进而改进你们的数学模型。4)假设连观测资料的时间变量也含有误差，试利用数据DATA4.TXT，建立数学模型，确定参数在某种意义下的最优解。2007-8-920:39#1Jxh助理工程师精华0积分39帖子20水位39技术分0DATA1:010.60.0.111.7508406503045180.13744802663822160.23.41333672578491767.1087059961201290.3000000000000000420.809218814387980.42515950828994240.45.2319824819454810.71823849314138270.526.92522160481810226.706603701525214DATA2:012.96228563303527472.123015833447770.17.55601031124052771.676575413353560.25.01238949657502248.239184640645720.300000000000000044.11510116028063927.7065260633840220.44.15751951139394415.7712968033598922/70.54.3712148823418128.547547743268050.60000000000000015.0973479460129375.0533632045674950.70000000000000016.0177422233737783.4273300696673940.87.0411809276363111.85245108531435370.98.6031013822982912.07977263131646241.10.2439776687138891.97011117744324761.112.1557764052522051.95310506352422331.200000000000000214.6670143159627463.16106675602404331.317.463975998120835.347913853436341.400000000000000119.35722339494480711.7637111023637061.519.315672007088531.6780078052271851.614.48763201419085666.162466730441741.70000000000000028.37805081556719875.209889621075221.85.28678169962056153.670387978434511.90000000000000014.20940120881974831.4211719632698772.4.25207326884724117.7695436914564942.14.3362189490105669.9584238388243062.25.014078765660765.3871506796545962.30000000000000035.7613228062276914.0407265520411182.40000000000000046.9045912853027632.30208030484945342.58.0291834361132232.1682553079086322.69.8085007754913091.759479732993372.711.8242551062662162.30150021469667232.800000000000000314.1256254405078072.2670987462774062.900000000000000416.9287180950969544.3712059553193.19.2347422448339539.8673633211949533.119.5863922587624425.6108576265580553.216.16806702104061358.776788747675163.30000000000000039.6685502689996176.871996440830123.40000000000000045.7823612952137359.579863243155723.54.43894157254283435.6495649180838263.64.12064088044657220.1952614459282783/73.74.35114160755416311.3292168094677023.80000000000000034.9227251797433566.3502528590626223.90000000000000045.7219127404920323.96441268588860534.6.4222644014239272.58239985470918844.10000000000000057.8237730881205762.09944674950054874.29.50977144951781.91550285326703684.311.3095680788547881.99595378648662614.413.5016042177542132.1910170627115554.515.9601238702873243.80634988376897134.600000000000000518.704944848470738.241824322691874.719.7658204814606120.5248949903297344.80000000000000117.16064000007436350.526206577550374.910.81684492846415976.721785356798965.6.48485858261624264.88423741778265.10000000000000054.36545564402284641.061577741074255.24.02754833713896123.460638446276415.3000000000000014.25173524316061613.142805432867885.44.7075568237447897.4240247730994615.55.5417287944486674.6213482704150635.6000000...
