The Erable libraries provide all the necessary high-level math programs that are not in the HP 48 ROM: symbolics: rational simplification and transcendental simplifications, factorization, derivative, including gradient of a function, integration: partial implementation of the Risch algorithm, Taylor series (extension of the in-build TAYLR instruction), Laplace and inverse Laplace transform, 1st order ordinary differential equation--symbolic or numeric matrices, eigenvalues and eigenvectors (including Jordan cycles of characteristic vectors), and much more. |
