Perform polynomial multiplication and simplify the results, show that ( x - 1 ) ( x + 1 ) ( x 2 + x + 1 ) ( x 2 + 1 ) ( x 2 - x + 1 ) ( x 4 - x 2 + 1 ) simplifies to x 1 2 - 1. Its not just a trivial speed increase, it is literally the. The Symbolic Math Toolbox supports the solving of equations and systems of equations using solve. You can substitute numeric values, other symbolic variables or expressions, vectors, or matrices. That is why you should avoid using the symbolic toolbox outside of a few select situations. The Symbolic Math Toolbox supports evaluation of mathematical functions by substituting for any part of an expression using subs. That puts the overall increase in speed at around a factor of 500x.

Most mathematical expressions can be represented in different, but mathematically equivalent forms and the Symbolic Math Toolbox supports a number of operations, including factoring or expanding expressions, combining terms, rewriting or rearranging expressions, and simplification based on assumptions. Now, what used to take over an hour to run using symbolic math takes about 8 seconds to run with a purely numeric approach. The Symbolic Math Toolbox supports the Formula Manipulation and Simplification of mathematical functions. Select Symbolic Math (in the left list box) and then Introduction (in the right list box). f (x) x.2 + 3x - 1 + 5x.sin(x) these next lines take the Anonymous function into a symbolic formula pkg load symbolic syms x ff f(x.
