自己编写的程序，运行后出现下列问题，请高手指教，程序见附件 Optimization terminated: first-order optimality is less than options.TolFun. f = 0 -1.4086 Warning: Default trust-region dogleg method of FSOLVE cannot handle non-square systems; using Gauss-Newton method instead. > In fsolve at 248 In swirlnozzle at 35 f = 0 -1.4086 f = 0 -0.3986 f = 0 -0.1218 f = 0 0.6373 f = 0 -0.1440 f = 0 -0.1218 f = 0 -0.1218 f = 0 0.1749 f = 0 0.0159 f = 1.0e-003 * 0 -0.8681 f = 1.0e-003 * 0 -0.8681 f = 1.0e-003 * 0 -0.8680 f = 1.0e-004 * 0 0.5751 f = 1.0e-003 * 0 0.4645 f = 1.0e-009 * 0 -0.1381 f = 1.0e-009 * 0 -0.1381 f = 1.0e-007 * 0 0.5120 Optimization terminated: directional derivative along search direction less than TolFun and infinity-norm of gradient less than 10*(TolFun+TolX). f = 0 -0.1066 Warning: Default trust-region dogleg method of FSOLVE cannot handle non-square systems; using Gauss-Newton method instead. > In fsolve at 248 In swirlnozzle at 45 f = 0 -0.1066 f = 0 0.0257 f = 0 0.0993 f = 1.0e-003 * 0 -0.3986 f = 1.0e-003 * 0 -0.3986 f = 1.0e-003 * 0 -0.3986 f = 1.0e-004 * 0 -0.6689 f = 1.0e-004 * 0 0.8004 f = 1.0e-011 * 0 -0.2870 f = 1.0e-011 * 0 -0.2870 f = 1.0e-007 * 0 0.1555 Optimization terminated: directional derivative along search direction less than TolFun and infinity-norm of gradient less than 10*(TolFun+TolX). 单位：mm 排放口直径=6.2,修正后的入口直径=6.2旋流半径=4.97,喷射角=48.5 0.5616 m选的合适，不需要再调整，m= 0.8000 参数合适，不需要调整 旋流室直径=16.2>> [ Last edited by csfn on 2008-12-29 at 20:10 ] |
