Matlab表达式化简
matlab计算表达式如下:
桥梁网络失效概率的计算表达式:B1*B2 + B1*B8 + B4*B8 + B2*B3*B4 - B1*B2*B8 + B1*B5*B6 - B1*B4*B8 + B1*B6*B7 + B4*B6*B7 - B1*B2*B3*B4 - B1*B2*B5*B6 - B1*B2*B6*B7 - B2*B3*B4*B8 - B1*B4*B6*B7 + B2*B4*B5*B7 + B3*B4*B5*B6 - B1*B5*B6*B7 - B1*B5*B6*B8 - B1*B6*B7*B8 - B4*B6*B7*B8 + B1*B2*B3*B4*B8 - B1*B2*B4*B5*B7 - B1*B3*B4*B5*B6 - B2*B3*B4*B5*B6 + B1*B2*B5*B6*B7 - B2*B3*B4*B5*B7 + B1*B2*B5*B6*B8 - B2*B3*B4*B6*B7 + B1*B2*B6*B7*B8 - B2*B4*B5*B6*B7 - B3*B4*B5*B6*B7 + B1*B4*B6*B7*B8 - B2*B4*B5*B7*B8 - B3*B4*B5*B6*B8 + B1*B5*B6*B7*B8 + B1*B2*B3*B4*B5*B6 + B1*B2*B3*B4*B5*B7 + B1*B2*B3*B4*B6*B7 + B1*B2*B4*B5*B6*B7 + B1*B3*B4*B5*B6*B7 + B1*B2*B4*B5*B7*B8 + B1*B3*B4*B5*B6*B8 + 2*B2*B3*B4*B5*B6*B7 + B2*B3*B4*B5*B6*B8 - B1*B2*B5*B6*B7*B8 + B2*B3*B4*B5*B7*B8 + B2*B3*B4*B6*B7*B8 + B2*B4*B5*B6*B7*B8 + B3*B4*B5*B6*B7*B8 - 2*B1*B2*B3*B4*B5*B6*B7 - B1*B2*B3*B4*B5*B6*B8 - B1*B2*B3*B4*B5*B7*B8 - B1*B2*B3*B4*B6*B7*B8 - B1*B2*B4*B5*B6*B7*B8 - B1*B3*B4*B5*B6*B7*B8 - 2*B2*B3*B4*B5*B6*B7*B8 + 2*B1*B2*B3*B4*B5*B6*B7*B8
该式要被执行很多次,如何化简改式,并提高运行效率,多谢!
如果你的算法中,该参数计算公式都没有办法简化
那matlab代码一样不能简化
从算法入手,能简化才行
