◼ N[expr] gives the numerical value of expr. ◼ N[expr, n] attempts to give a result with n‐digit precision. ◼ Unless numbers in expr are exact, or of sufficiently high precision, N[expr, n] may not be able to give results with n‐digit precision. ◼ N[expr, n] may...
factoring, factorisation, factorization - (mathematics) the resolution of an entity into factors such that when multiplied together they give the original entity extrapolation - (mathematics) calculation of the value of a function outside the range of known values interpolation - (mathematics) calculati...
The same is true for symbolic computation. If you don’t care about the symbolic answer and are not worried about stability, then substitute numerical values as soon as you can. For example, solving this polynomial symbolically before substituting the values in causes Mathematica to produce a fiv...

An example of such a problem is one where the solution is a specific numerical value, and the accuracy of this value depends on the precision of the performed calculations. It turns out that such a suitable problem could be a sum of irrational numbers. Let us look at the following sum: ...
Remark: Numerical value readings over technical plots or charts seem to be often wrong. Often enough, OpenAI’s vision model warns about this in the responses. Formatted output Here we make a function with a specially formatted output that can be more easily integrated in (larger) workflows: ...
In this article, we will show how to use the software package Mathematica to understand the power method in linear algebra or numerical analysis. The power method enables one to find the eigenvalue with the largest absolute value of a given matrix, and a corresponding eigenvector. We will ...
One way to check the validity of the numerical estimates is to compare the computed value of the REE to the negativity, another well-known entanglement monotone. This is defined as N (ρ) = Tr |ρ | − 1 2 . 9 被引用 · 0 笔记 引用 Random Sampling of Quantum States: a Survey ...
Nature of physical problem: Solution of partial differential equations in three space dimensions, which are formulated as an initial value problem. In particular, the program is geared towards handling very complex tensorial equations as they appear, e.g., in numerical relativity. The worked out ex...
In the Wolfram Language, we’ve always taken special functions very seriously, not only supporting a vast collection of them, but also making it possible to evaluate them to any numerical precision, and to have them participate in a full range of symbolic mathematical operations. When I first...
