R has three packages that are useful for solving partial differential equations.
solve() function solves equation a %*% x = b for x, where b is a vector or matrix.
In the sections that deal with the use of R for solving differential equations, we have taken examples from a variety of disciplines, including biology, chemistry, physics, pharmacokinetics. Many examples are well-known test examples, used frequently in the field of numerical analysis.
Basic Application of solve() Function in R. In this Example, I’ll illustrate how to apply the solve … account of how to solve a large variety of differential equations, comprising ordinarydifferentialequations, initial value problemsand boundaryvalue problems, differential algebraic equations, partial differential equations and delay differential equations. The solution of differential equations usingR is the main focus of this book. It is Published on Aug 2, 2013.
