Some Explicit Formulas for Matrix Exponential, Matrix Logarithm, the th Power of Matrices and their Drazin Inverses
Mohammed Mouçouf, Said Zriaa
In this work, new closed-form formulas for the matrix exponential are provided. Our method is direct and elementary, it gives tractable and manageable formulas not current in the e…
