Keywords:
Drazine inverse, exponential matrix, generalized inverse, Linear equationsAbstract
The Drazin Inverse is a generalized form of inverse that shares similar properties with a square matrix; hence, the Drazin inverse is only defined for a square matrix. The Drazin inverse has numerous applications in solving singular differential equations, Markov chains, and iterative methods in numerical analysis. In the case where the system involves a matrix that is invertible, if matrix is singular or non-invertible "Certainly! The corrected text is: "inverse, denote"e, the Drazin inverse is utilized to solve the system above. The research aim is to utilize the Drazin inverse in solving first-order singular linear differential equations. Let and be matrices, a vector-valued function. and may both be singular. The differential equation is examined using the theory of the Drazin inverse. closed form expression for all solutions of the differential equation is provided when the equation has unique solutions for consistent initial conditions. This is a review article and the results show that to solve single linear differential equations, the inverse of Drazin is the best possible way to solve this type of differential equations.
