Based onfirst-order optimization calculating theory,authors established the optimal finite element model of swivel construction of arch bridge adopting hydraulic sync elevation technology. 根据一阶最优化计算理论,构建了采用液压同步提升技术进行转体施工拱桥的优化有限元模型。
对偶空间与双重对偶空间:向量空间上的线性泛函构成对偶空间,用符号表示。给定向量空间,其内积与对偶空间内积保持一致。对偶范数定义为线性泛函在单位球面上的最大内积值。引理证明了广义不等式成立。在有限维空间,双重对偶空间与原始空间同构,双重对偶范数与原始空间范数一致。伴随变换定义:给定向量空间与...
1运行matble出现Optimization terminated:first-order optimality is less than options.TolFun.咋改?本身就是新手,我百度了一下说是超出精度的问题,还请大神指点一下(最好是带着修改完之后的图看看,f=@(x)1100*exp(-0.1386*x);h=@(x)6600*exp(-0.1155*x)-6600*exp(-0.1386*x);g=@(x)1650*exp(-0.138...
使用ode45()的格式和要求:首先,ode45()函数的完整格式应为 [t,y]=ode45(odefun,tspan,y0,options,p1,p2,p3,.。。。)其二,有p1,p2,p3,.。。。(附加传递参数)时,odefun()应表示为f(t,y,p1,p2,p3,...)
