The direct solution produces We would like to show you a description here but the site won’t allow us. 此 MATLAB 函数 计算方阵 X 的逆矩阵。 Sep 26, 2018 · I'm trying to compute an inverse of a matrix P, but if I multiply inv(P)*P, the MATLAB does not return the identity matrix. 在 Matlab 中， inv 命令用于求解方阵的 逆矩阵。如果矩阵 A 是可逆矩阵（即 行列式 不为0），那么它的逆矩阵 A^ {-1} 满足 AA^ {-1}=A^ {-1}A=I ，其中 I 为单位矩阵。 具体来说，如果 A 是一个 n \times n 的方阵，那么 inv(A) 将返回一个 n \times n 的矩阵，即 A 的逆矩阵。需要注意的是，对于 病态矩阵 或高维矩 Jul 1, 2014 · what is the difference between those functions and which one is more precise? sometimes matlab show warning while using the inv function with a suggestion to use the backslash insted. inv handles both continuous- and discrete-time systems. inv(sys,'min') inverts sys to eliminate the extra states and obtain a model with as many states as sys or A respectively. The math didn’t break, the data did. You should use x=A\b for an over- or under-defined system, or one which is badly conditioned. Being able to reliably compute inverse matrices unlocks capabilities to solve systems of equations, transform coordinates, […] This MATLAB function computes the inverse of square matrix X. The result is a symbolic matrix function of type symfunmatrix that accepts scalars, vectors, and matrices as its input arguments. Inverse of a matrix in MATLAB is calculated using the inv function.
