① 如何用MATLAB 的PDE toolbox求解三维热传导方程
这个问题可以用matlab自带的PDE工具箱解决，里面专门有处理热传导的模块。 如果你需要的话，我可以给你发一份PDE工具箱的使用介绍，里面有处理二维热传导问题的例题，需要的话请追问并留邮箱地址
② 用MATLAB如何导入solidworks做出的三维模型
MATLAB是数据处理软件，sw是三维建模软件通用的三维导入格式igs/stp不能用。MATLAB可以识别sw另存为的XML文件。sw的xml文件需要用MATLAB安装插件，再用SW调用才能生成XML 和若干个STL文件。

MATLAB软件中应该有的，用命令“doc graph3d”或者“help graph3d”，之后出现：

④ matlab 3d world editor怎么用
打开World Editor，选择高级，选择游戏平衡常数，找英雄最大等级，自己填写想要的数字。技能等级修改：打开模块，选择物体编辑器，选择技能，找到你要修改的技能，单击之后在该技能的面板里找到“状态（s) --等级”，默认一般技能是3，你改成10，然后下面就会自动出现“等级4-数据”等一直到“等级10-数据”，而且下面的影响区域、持续时间等都要你自己设置数据，
⑤ matlab中kriging工具箱用法
% xn, yn, zn - coordinates of the input data
代表输入的变量 xn, yn, zn 是输入数据的空回间坐标答
xp, yp, zp 是输出kriging点的坐标

⑦ 为什么matlab2014没有vr工具箱
在workspace下打vrinstall -install viewer %安装浏览器matlab会提示你是选择OpenGl加速还是Direct3d加速，按o或d选择选择完后，会出现blaxxun Contact viewer的安装程序如下，将它装上即可
再打vrinstall -install editor %安装制作器，用vrinstall -install会将两者都装上
可以用命令vrinstall -check检查是否安装成功；安装过程似乎比较长啊，尤其是装viewer的时候。>> vrinstall -install
Installing blaxxun Contact viewer ...
Do you want to use OpenGL or Direct3D acceleration? (o/d) d
Starting viewer installation ...
Done.
Starting editor installation ...
Done.>> vrinstall -check
External VRML viewer: installed
VRML editor: installed可以在matlab的Preferences中查看使用的VRML editor ，还可以做出修改，如下 第二步：制作一个包含小球的三维模型
打开<matlab root>\toolbox\vr\vrealm\program\vrbuild2.exe %<matlab root>为matlab安装的路径，我的matlab是最新的2011版本，此文件路径为toolbox\sl3d\vrealm\program\vrbuild2.exe
然后ctrl+N(点file菜单下的new也可以，表示新建一个三维实体),选中左边的New world,然后点击工具栏上图标为一个球的按钮，即添加了一个小球（你也可以添加其他的）将左边的transform改成ball(名字而已），此时你可以看到它下面有一些center、rotation、scale、scaleOrientation、translation等等，这些就是matlab下可以控制的（下一步将介绍）。此时你可以修改这个小球的大小，位置，颜色等。还可以添加一些其他的三维实体，像灯光、fog、背景、视角等等。这儿就不介绍了，随便你们怎么玩吧。此时点击保存，这儿我保存为ball.wrl,wrl文件是vrml格式（vrml格式其实就是跟html一样，一种固定格式，只是面对的对象不同，你可以用文本编辑器看看它的格式）另外还可以
