数据文件test.xls在附件里，源程序为
% solve the equation
function Calculate
A = [1 1 1;620 182 400;1 2.65 2.2];
b = [1;0;0];
X = zeros(939,3);%赋值
temp = xlsread('test.xls');
for i = 1: 939
b(2,1) = temp(i,1);
b(3,1) = temp(i,2);
B = A\b;
%fprintf(1,'第 %d 行 M,N对应的X1，X2，X3结果：\n',i);
for j = 1:3
X(i,j) = B(j,1);
%fprintf(1,'%5.4f\n',X(j,1));
end
end
X
%fid = fopen('result.xls', 'w+');
%fid = fopen('result.txt', 'w+');
%fwrite(fid,X);
%fclose(fid);
xlswrite('result.xls', X);

错误信息：
??? Error: File: D:\matlab6.1\toolbox\matlab\iofun\xlswrite.m Line: 88 Column: 16
Expected a variable, function, or constant, found "&".

Error in ==> D:\matlab6.1\work\Calculate.m
On line 22 ==> xlswrite('result.xls', X);
自己已经在D:\matlab6.1\toolbox\matlab\iofun与D:\matlab6.1\toolbox\matlab\iofun\ja
下加入xlswrite函数，应该不会提示错误，难道是底版本的matlab不能加入xlswrite函数？
烦请各位能解释一下？

7.1中能在EXCEL写X = zeros(939,3)，xlswrite('result.xls', X);

楼主可以尝试直接写某一数据集，如若不行，很可能是版本的问题
