3D plot problem in Matlab

Dear all dF^`6-K1  
E8.1jCL>{"  
I try to plot a 3D surface in matlab by this command
VO<P9g$UD  
first I import the txt file in matlab and then : 1`9'.w+r  
op,mP0b  
IIAm"=*  
x=data(:,1); X CHN'
l'  
>> y=data(:,2); J@IF='{  
>> z=data(:,3); 0BN=>]V~j7  
>> SAR=data(:,4); p@3 <{kLm  
>> [X,Y,Z]=meshgrid(x,y,z); iwfH~  
surf(X,Y,Z,SAR); W"g@*B'|  
lGEfI&1%!  
but I face with this error : HHZrovA#  
8p]Krs:  
??? Maximum variable size allowed by the program is exceeded. U3pMv|b

Error in ==> meshgrid at 60 r#c+{yY

how can I solve it? w"!zLB&9[

after that I faced that error I used  this command to determine how much is the free memory space ? {;ur~KE

and there is the result about space in the memory : UP |#WegO

so,why I face with this error!? UP}5Eh  

Matlab帮助文件里并没有说meshgrid有长度限制，因此你要考虑的是导入赋值的x, y, z有没有超过软件对变量名长度的限制，这一点你并没有说明。

dear hefang hRTw8-wy:  
thanks for your reply nI.K|hU:P

I attached my txt file may you  to look it. .Nz2K[

I don't understand what you mean: S[(Tpk2_  
:["iBrFp  
"import assignment x, y, z have no more than the software limit on the length of variable names, which you did not specify." 8)HUo?/3  
d\dh"/_$  

看你总是用英文留言，为什么不耐心理解一下软件给你的提示呢？提示信息说allowed by the program，以我的理解，这个限制不是源自meshgrid这个函数，而是因为Matlab这个程序。假设这个导入的数据里有2亿个数据项，你觉得正常的软件能处理么？ t<=Ru*p

什么附件？有这么忙么，发完就走人也不看看帖子是不是完整？

希望能仿真吧
