h**********c 发帖数: 4120 | 5 SCILAB, pyplot(python), coin3d什么以前都搞过。
qt+ opengl 写过project. 3d 到2d 就是一视角和投影得选择,图形加速都是三维处理
,投影,具体pipeline 忘了。
处理过GB level 数据。linux 内存卷, C++ OPenGL.好长时间不碰了。 |

r**m 发帖数: 1825 | 6 Freemat 的绘图功能差些,
Octave 和scilab 都不错,但是octave用gnuplot,所以
绘图方面强一些。 |

a******s 发帖数: 232 | 10 ft,scilab is free to download. Why do you say it's hard to download? |
|
c**z 发帖数: 1014 | 11 matlab can do that easily,
use the command eig.
If you don't have matlab,
maybe you can try scilab, which I think is free. |

P*******t 发帖数: 202 | 12 人是一个大牛num analysis教授推荐用octave |

D********g 发帖数: 533 | 15 Thanks. I've read this before. But the problem is softwares they use are too
obselete. :) |
|
x*****u 发帖数: 3419 | 16 Can't you do something similar? It is just a benchmark.
Anyway, I have no experience of scilib, but I like octave.
too |

o*******e 发帖数: 186 | 17 As far as I know, there is free version of Octave for windows available. |

h***z 发帖数: 233 | 19 Yeah, just switch to Python if you don't mind learning a new syntax (which
is quite easy with Python). Python with numpy has similar performance as
the commercial Matlab for matrix operations, but is much faster (and much
nicer to code in) for general scripting. Also, since it's a general
programming/scripting language with great libraries for pretty much anything
you can think of, it can be used as a unified solution for all your needs (
e.g. data acquisition, report generation, system monito |

h**********c 发帖数: 4120 | 20 sci 功能太少,不过基本的数学运算都有,不要钱,开源;
matlab 功能太多,多到80-90%用不上,很贵;
底层的东西都是fortan库,不如直接啃fortan |

j****n 发帖数: 40 | 22 因为比较熟悉matlab,却又不想麻烦申请新的license(需要一些手续,还要花钱,老
板要考虑),想把盗版matlab装上(自己的电脑,Linux,不过在学校里用,会联学校的网的),不知道
有没有问题,比如matlab 2009会不会时不时地连上他自己的服务器,像windows一样来
个啥genuine检查?(ps. 版本2009,新弄得,似乎license管理跟以前不太一样了?)
其实我也不想,实在是不方便,嗬嗬!
顺便说下现有的免费软件:
现在正在试着用scipy/numpy,还有sage,不知道有没有人用过sagemath?似乎要跟
matlab PK的免费软件。不过我用了几下,发现数学基本的东西应该很全,不过针对个
别matlab下的toolbox,就显得太少了。
octave和scilab,尤其是octave,我说不上喜欢或是不喜欢,说是根matlab兼容,所以
经常有种错觉就是用matlab来写,不过不断的出现各种小问题,help也不太方便,不如
python来得方便,扩展性也不错,还能写GUI用来demo.
大家有啥建议? |

g****t 发帖数: 31659 | 24 octave写的code放matlab里面不用改基本上就能用.反之亦然.
相比之下,scilab兼容性差很多.
这个才是正解…… |

s****h 发帖数: 921 | 26 我有几个简单的控制diagram.
output = input * sT1/(1+sT1) / (1+sT2)
input是时间轴上的信号,40seconds的信号,每second有250个取样。
我想搞个软件,计算出output.
可是我没有simulink.
刚刚试验了下Scilab Xcos,感觉不会用,弄不出来。
有什么好建议? |

q**j 发帖数: 10612 | 28 打算写一个 EXCEL application。让用户在 Excel 里面输入一些parameters,然后把
这些东西给Matlab。计算完以后,把结果再返还到Excel里面去。Code写完以后把所有
的东西都compile一下,做成一个Excel的plug-in。以后用户在用的时候就不需要用
Matlab了。So far so good,但是Mathworks居然两个compliler要卖10k plus。请问有
没有别的软件可以代替Matlab here?我可以想到的是R,Scilab, Octave,Python etc。
当然
1.这些软件是free的,所以也许不别要做成 Excel plug-in。但是他们有没有这个能力?
2.如果这些东西自己可以写GUI的话,有没有办法抛弃Excel呢?
请大侠指点一下吧。 |
