Matlab的solve()函数的使用方法 1.首先是对方程的求解 不废话直接上例子 syms x: eq=x^2+2*x+1; s=solve(eq,x); 结果如下 完美的算出了方程的解 现在对上面的代码进行一些说明 1.syms x:是必要的,这将会把x设为符号变量. 2.eq=x^2 +2x+1;eq也会变为一个符号变量用于储存方程 x^ 2+2x+1 2.s=solve(eq,x):中方程的结果由solve函数返回,存储在s里.注意(eq,x)中x是说明eq这个方程中x为变量. 这个看

Sometimes when you open a VS2010 project, an error window will pop up with the error message "Exceptions has been thrown by the target of an invocation" which is weird. The easy way to solve this and get your project started normally is: 1) Open

当选择static solve的时候,求解的流程如下: 1.获得内力 2.qresidual = 外力-内力,qdelta = qresidual, qdelta的非约束元素赋给bufferConstrained 3.用tangentStiffnessMatrix给systemMatrix A赋值 4.求解A * buffer = bufferConstrained 5.把buffer指定为qdelta不受约束的部分 由此可见,实质上是求解 tangentStiffnessMat * dx =
