请问一下运行后提示的出错信息是什么意思啊?怎么样去修改呢

a=fscanf(fid,'%g%g%g'm3,inf); 有错误
参见下面：
The example in fprintf generates an ASCII text file called exp.txt that looks like
0.00 1.00000000
0.10 1.10517092
...
1.00 2.71828183
Read this ASCII file back into a two-column MATLAB matrix:
fid = fopen('exp.txt', 'r');
a = fscanf(fid, '%g %g', [2 inf]) % It has two rows now.
a = a';
fclose(fid)
