Extract complete argument and function name(s) from the Expression, (standard mathematical functions only) MAPLE

由 允我心安 提交于 2019-12-02 22:33:27
问题 For expressions like a1 := sin(1+a/b); a2 := log(1+ a*b); a3 := abs(a^2+b); how can I get expressions of respective functions. For example someCommand(a1) # should get an output 1+a/b someCommand(a2) # should get an output 1+a*b someCommand(a3) # should get an output a^2+b I have tried to get related topics from maple documentation but unfortunately am not able to get exactly. edited: Also how is it possible to get list (in sequence)of functions used let a :=sin(log(abs(a+b)));# functions can

看参考书到第五章，后面的是爱看不下去了，需要数学功底 解方程 二维三维图形 微分与积分 微分方程 数据处理（统计） maple编程 maple在计算和解方程方面具有巨大优势，适合于大学以上学历人员使用 适合于数学方面的人员使用，其他方面的人员把它当做一个工具即可 也可以算是一个编程语言吧（类似于matlab）。 如果你每天面对大量高等数学，矩阵，微分方程组等的求解，建议学习一些基础的函数，会计算即可。 网上的资料并不多，中文资料更少，不如matlab的大众化 学习要有恒心。 来源： https://www.cnblogs.com/yanbeiyinhanghang/p/11732914.html

TPO4-1 Deer Populations of the Puget Sound

由 北战南征 提交于 2019-12-02 02:56:53
The causes of this population rebound are consequences of other human actions. First, the major predators of deer-wolves, cougar, and lynx-have been greatly reduced in numbers. Second, conservation has been insured by limiting times for and types of hunting. But the most profound reason for the restoration of high population numbers has been the fate of the forests. Great tracts of lowland country deforested by logging, fire, or both have become ideal feeding grounds of deer. In addition to finding an increase of suitable browse, like huckleberry and vine maple, Arthur Einarsen, longtime game

Finding the shortest repetitive pattern in a string

由 久未见 提交于 2019-12-01 17:39:18
I was wondering if there was a way to do pattern matching in Octave / matlab? I know Maple 10 has commands to do this but not sure what I need to do in Octave / Matlab. So if a number was 12341234123412341234 the pattern match would be 1234 . I'm trying to find the shortest pattern that upon repetiton generates the whole string . Please note: the numbers (only numbers will be used) won't be this simple. Also, I won't know the pattern ahead of time (that's what I'm trying to find). Please see the Maple 10 example below which shows that the pattern isn't known ahead of time but the command finds

一、版本控制 说到版本控制，脑海里总会浮现大学毕业是写毕业论文的场景，你电脑上的毕业论文一定出现过这番景象！ 1 2 3 4 5 6 7 8 9 10 11 毕业论文_初稿.doc 毕业论文_修改 1.doc 毕业论文_修改 2.doc 毕业论文_修改 3.doc 毕业论文_完整版 1.doc 毕业论文_完整版 2.doc 毕业论文_完整版 3.doc 毕业论文_最终版 1.doc 毕业论文_最终版 2.doc 毕业论文_死也不改版.doc ... 以上就是使用最原始的方式进行版本控制，但是这种方式有显著缺点： 多个文件，保留所有版本时，需要为每个版本保存一个文件... 协同操作，多人协同操作时，需要将文件打包发来发去... 容易丢失，被删除意味着永远失去...（可以选择网盘） 为了解决以上版本控制存在问题，应运而生了一批版本控制工具：VSS、CVS、SVN、Git等，其中Git属于绝对霸主地位。 注意：一般版本控制工具包含两部分 客户端（本地）：本地编写内容以及版本记录 服务端（网盘）：将内容和版本记录同时保存在远程（可有可无） 二、GIT介绍 Git 是一个开源的分布式版本控制软件,用以有效、高速的处理从很小到非常大的项目版本管理。 Git 最初是由 Linus Torvalds 设计开发的，用于管理Linux内核开发。Git 是根据GNU通用公共许可证版本2的条款分发的自由

Grabbing the output of MAPLE via Python

由 只谈情不闲聊 提交于 2019-12-01 05:54:32
问题 How would I use the subprocess module in Python to start a command line instance of MAPLE to feed and return output to the main code? For example I'd like: X = '1+1;' print MAPLE(X) To return the value of "2". The best I've seen is a SAGE wrapper around the MAPLE commands, but I'd like to not install and use the overhead of SAGE for my purposes. 回答1: Trying to drive a subprocess "interactively" more often than not runs into issues with the subprocess doing some buffering, which blocks things.

3D curvefitting

由 天大地大妈咪最大 提交于 2019-11-27 07:53:04
I have discrete regular grid of a,b points and their corresponding c values and I interpolate it further to get a smooth curve. Now from interpolation data, I further want to create a polynomial equation for curve fitting. How to fit 3D plot in polynomial? I try to do this in MATLAB. I used Surface fitting toolbox in MATLAB (r2010a) to curve fit 3-dimensional data. But, how does one find a formula that fits a set of data to the best advantage in MATLAB/MAPLE or any other software. Any advice? Also most useful would be some real code examples to look at, PDF files, on the web etc. This is just

What is the fastest factorization algorithm?

由 我与影子孤独终老i 提交于 2019-11-26 21:29:32
I've written a program that attempts to find Amicable Pairs. This requires finding the sums of the proper divisors of numbers. Here is my current sumOfDivisors() method: int sumOfDivisors(int n) { int sum = 1; int bound = (int) sqrt(n); for(int i = 2; i <= 1 + bound; i++) { if (n % i == 0) sum = sum + i + n / i; } return sum; } So I need to do lots of factorization and that is starting to become the real bottleneck in my application. I typed a huge number into MAPLE and it factored it insanely fast. What is one of the faster factorization algorithms? Sam Harwell Pulled directly from my answer
