why loop missing or extra characters
显示 更早的评论
w0=ones(4000,1)
A=readmatrix('matrix.txt')
count1=0
count2=0
while
time1=tic
[lam,i]=powereig(A,w0,1)
fprintf('With the tolerance set to 1, the estimated eigenvalue is:%f',i)
count1=count1+1
fprintf('Iteration count:%d',count1)
break
end
while
time1=tic
[lam,i]=powereig(A,w0,10^-5)
fprintf('With the tolerance set to 1, the estimated eigenvalue is:%f',i)
count2=count2+1
fprintf('Iteration count:%d',count2)
ftime2=toc
fprintf('powereig() Time Elapsed:%d',ftime2)
break
end

Invalid expression. Check for missing or extra characters.

You need to have a condition for the while statement that tells it when to continue or quit the loop. You have just a bare while with no condition at all after it!
