matrix inverse的用法和樣例：
例句
- The new algorithm is non-iterative, and it needs the FFT algorithm and the inverse of little-size matrices.
不需要迭代，不需要預條件處理，計算過程中主要採用快速傅里葉變換及小矩陣求逆，計算效率高。 - The property of symmetry can also be used to save a part of the computational effort required for matrix inversion or for a solution of equations.
對稱的特性也可用來節省矩陣求逆中或求解方程中所需要的一部分計算量。
