replaced by a vector x, then the determinant of the resulting matrix is the kth entry Since det A = 1, the inverse formula in Theorem 8 shows that all the entries in 1 [M] MATLAB Student Version 4.0 uses 57,771 flops for inv A and 14,269,045 

but since it is not a square matrix when i use S^-1 it says i have to use elemental wise power. If the matrix A does not have full rank, there is no inverse. In consequence you cannot find any B, which satisfies A*B=eye . This is the definition of the rank, of invertible and there cannot be an "alternative".

2020-06-17 · To take the inverse of a matrix in Matlab®, you need to use the “inv ()” command. It will generate the inverse of a matrix if you write the name of this matrix in this code in Matlab®. ‘a’ is the normal matrix created by us in Matlab® as shown above. ‘b’ is the matrix that we take as the inverse of ‘a’.

In Matlab, the Inverse function is obtained by applying the ‘ finverse ’ command. This command returns the value of the given function variable. The inverse would be an ugly looking matrix with lots of terms in it.

MATLAB uses Gauss elimination to compute the inverse of a general matrix (full rank, non-sparse, without any special properties) using mldivide and this is Θ(n 3), where n is the size of the matrix. So, in your case, n=5000 and there are 1.25 x 10 11 floating point operations.
