Algebra. Evaluate log base 3 of 4. log3 (4) log 3 (4) The change of base rule can be used if a a and b b are greater than 0 0 and not equal to 1 1, and x x is greater than 0 0. loga(x) = logb (x) logb(a) log a (x) = log b (x) log b (a)
In mathematics, a logarithm of a matrix is another matrix such that the matrix exponential of the latter matrix equals the original matrix. It is thus a generalization of the scalar logarithm and in some sense an inverse function of the matrix exponential.
12 wrz 2015 · We want to calculate an approximation of $\log(A)$, the principal log of $A$. There is (eventually) an instability (in the calculation) when the eigenvalues of $A$ are close or when the matrix of change of basis (to obtain a diagonal form, otherwise a Jordan form) has a large condition number.
