4)科研中解方程组时Solve遇到的问题:当方程中的系数等都是很复杂的小数时,此方程组无法用solve得到自洽的精确的解!此时只有自己在纸上解方程组!!! a.output解集为空的原因是:这些方程中的系数等都是很复杂的小数,所以这个方程组无法用solve得到自洽的精确的解!此时只有自己在纸上解方程组!!! b.提示信息:“So...
the cases are very simple, and only contain a few simple letters, and the rest are numbers, so I am thinking Could it be that Solve can't solve my type of equation system. Then I looked at the tutorial on understanding equations and...
2.3 Find a1, a2, b1, b2 in equation (21) Figure 13 Although the optimal control variable value is obtained, L1 and L2 have not been solved yet. Referring to the original paper, I first express the HJB equation satisfied by the manufacturer and the retailer according to the obtained co...

Through the experiment with Mathematica solving system of linear equations and input formats of all kinds of ordinary differential equations and some problems that should be paid attention to, Ordinary differential equation solution more intuitive、Simple and efficient, That mathematics experiments using Mat...
boolean result = equation.solve(values); if (result) { System.out.println("方程不等式成立"); } else { System.out.println("方程不等式不成立"); } } } ``` 在Main类中,我们定义了一个包含两个变量的方程不等式,并通过Equation类求解了给定变量值下的结果。根据不等式的成立情况输出相应的提示信息...
