kääntömatriisi
Kääntömatriisi, or inverse matrix in English, is a fundamental concept in linear algebra. For a square matrix A, its inverse, denoted as A⁻¹, is a matrix such that when multiplied by A, it results in the identity matrix I. The identity matrix is a square matrix with ones on the main diagonal and zeros elsewhere. The equation is A * A⁻¹ = A⁻¹ * A = I.
Not all square matrices have an inverse. A matrix that has an inverse is called an invertible
The process of finding the inverse of a matrix can be done through various methods, including Gaussian
Inverse matrices have numerous applications in mathematics and science. They are crucial for solving systems of
