The inverse of a matrix A is A⁻¹, just as the inverse of 2 is ½. We can solve equations by multiplying through by inverses; it's similar with matrices.
Using thesolve()Function to Find the Inverse of a Matrix in R In R, you can compute the inverse of a matrix using thesolve()function. Thesolve()function takes one argument, which is the matrix you want to invert. Here’s the basic syntax: ...
inverse这里指的是求这个3阶方阵的逆阵。具体方法就是初等变化，如果你会的话，方法如下：假设这个方阵是A，3阶的单位方阵为E，那么 A|E-->E|B。这里的B就是所求的逆阵。做法就是利用行初等变化把A变成E，同时用相同的行初等变化就把E变成了B。在理论上很好解释。这一系列的行变化就相当于B*...

所以(6ax+2b)+(3ax^2+2bx+c)=2x^2+1 所以3a=2,6a+2b=0,2b+c=1 a=2/3,b=-2,c=4 故特解为Y=2/3x^3-2x^2+4x 原方程对应齐次方程的特征方程为r^2+r=0 r=-1或r=0 所以齐次方程的通解为y*=C1e^(-x)+C2 原方程的通解为y=C1e^(-x)+C2+2/3x^2-2x^2+4x ...
