关于matlab中交互输入的问题？？

roumots

本人刚刚学习matlab,正在编写一个扫雷的程序，还不会gui，是基于字符的，可以自己玩，也可以让电脑来自动扫！

不过在input上遇到了问题，每次运行到input 语句的时候显示如下：

??? Index exceeds matrix dimensions.

Error in ==> minesweeper at 11
    xx=input('Please input x!');

希望大家帮个忙！！

程序如下（未完成）：

function step=minesweeper(x,y,input)%falied!
tag=input('1-Play by yourself!  2-Play by AI!');
matrix=minemap(x,y,input);
matrix1=zeros(x,y);
matrix1=matrix1-100;%Matrix1 is the matrix that you can see on screen!
disp(matrix1);
have=0;
if tag==1
  while check(have,matrix1,matrix)~=input
    have=check(have,matrix1,matrix);
    xx=input('Please input x!');
    yy=input('Please input y!');
    ju=input('please input judgement:1 0r 0!');
    matrix1=returnmap(matrix,xx,yy,ju);
  end
if have==input
     disp('You have successed!!');
else
     disp('To be continued.......');
end
elseif tag==2
  step=autoplay(matrix);  
  return;
end



function step=autoplay(inmatrix)%failed!
step=1;
[m,n]=size(inmatrix);
x=round(rand*(m-1))+1;
y=round(rand*(n-1))+1;
mat=returnmap(inmatrix,x,y);
if mat==0
    step='Failed';
    return;
end
while mat~=0 %?????
   
end

   
   
   
function outmatrix=minemap(x,y,input)%successful!
%First,we have to make the out!
totol=x*y;
out(1,1)=round(rand*(totol-1))+1;
for i=2:1:input
    long=length(out);tapp=1;
    while tapp==1
       tap=1;
       number=round(rand*(totol-1))+1;
       for j=1:1:long
           if out(1,j)==number
               tap=0;
               break;
           end
       end

你希望输入的是什么东西

问题解决!
谢谢大家！！
