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. So on a reasonable machine with about 10 Gflops of computational power, you're going to require at least 12.5 seconds to compute the inverse and there is no way out of this, unless you exploit the "special properties

Consider two system of nonlinear equations. In this case we will get F(x1, x2)=[c1 c2] ^T; Based on my problem, I need to calculate The inverse of such a matrix will not be binary. Perhaps you want to operate in GF(2), so the field of integers, mod 2. INV is NOT designed to solve that problem, and while it is indeed possible (assuming the matrix is non-singular in GF(2)), do you really want to do that? Naturally, Matlab has appropriate and fast instructions to perform matrix inversions (as with 'inv' or '\', for example), but we want to explain the Gauss-Jordan concept and show how nested loops and control flow work.

When computing the inverse for some square matrix A in MATLAB, using. Ai = inv(A) % should be the same as: Ai = A^-1 MATLAB usually notifies me that this is not the most efficient way of inverting. So what's more efficient? If I have an equation system, using the /,\ operators probably is. But sometimes I need the inverse for other computations.

Inversa de la matriz Una matriz X es invertible si existe una matriz Y del mismo tamaño tal que X Y = Y X = I n, donde I n es la matriz de identidad de n por n. La matriz Y se denomina la inversa de X. Una matriz que no tiene inversa es singular.
The inverse of a matrix A is denoted by A −1 such that the following relationship holds −. AA −1 = A −1 A = 1 The inverse of a matrix does not always exist. If the determinant of the matrix is zero, then the inverse does not exist and the matrix is singular.
