在 MATLAB Online 中打开

Rather than loading the digits from the text file, couldn't you get them directly from within Matlab?

p = sym(pi);
piVpa = vpa(p,1000001); 
piChar = char(piVpa);
% put all decimal places into a vector (might take several seconds)
pidp = str2double(cellstr(piChar(3:end)'));  

UPDATE: when compared with Stephen Cobeldick's solution using isequal(vec, pidp), the results are the same. However, Stephen's solution is much faster. My solution would be a good plan-b if you don't have a text file available.

data.txt

This code imports all of the digits in around one second:

>> fid = fopen('data.txt','rt');
>> vec = fscanf(fid,'%1d');
>> fclose(fid);
>> numel(vec)
ans =  1000000
>> vec(1:10) % first ten digits
ans =
   3
   1
   4
   1
   5
   9
   2
   6
   5
   3
>> vec(end-9:end) % last ten digits
ans =
   0
   5
   7
   7
   9
   4
   5
   8
