Matlab在按下上图输入之后不会等待用户输入

Question

因此，我有一些代码曾用于以前版本的Matlab，但现在在R2015a版本中不再适用。

该代码允许用户单击图片以获得所需数量的点的像素坐标，然后通过用户输入功能，用户可以给出这些点在世界坐标上的世界坐标。

事情是，当我按下“Enter”键来确认阶段的最后一个点时，它会停留在缓冲区，当输入部分出现时，matlab认为我按下了输入而没有时间给出该坐标。

我试着用set(gcf,'CurrentCharacter','char(0))来解决这个问题，但它不起作用。

如果我使用“调试”模式，我停在输入线：它的工作原理。

npoints = input('How many points do you want to select in the picture ? ') ; 
refpoints = cell(1,npoints); 

for i = 1:npoints % this bit of code allows the user to zoom on a figure, press escape 
% when he's done zooming, click on the desired point and then press enter to confirm 
    fig = figure ; 
    imshow(picture) 
    zoom on; 
    waitfor(gcf,'CurrentCharacter',char(27)); 
    zoom off 
    refpoints{i} = ginput(1); % select point round to the closest pixel 
    waitfor(gcf,'CurrentCharacter',char(13)); 
    close(fig); 
end 

%%%%%%%%%%%%%%%%% 
% Cell2array... % 
%%%%%%%%%%%%%%%%% 

x1 = zeros(npoints,1); % pixel coordinates 
y1 = zeros(npoints,1); 

for k = 1:size(refpoints,2) 
x1(k) = round(refpoints{1,k}(1)); 
y1(k) = round(refpoints{1,k}(2)); 
end 

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% 
% Calculating the world coordinates % 
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% 

disp('Now you need to give the physical coordinates to each of the points specified!') 
disp('-----------------------') 

world = zeros(npoints,2); 
X1 = zeros(npoints,1); % Real world coordinates 
Y1 = zeros(npoints,1); 

fig1 = figure ; 
for jj=1:npoints 
imshow(picture); 
hold on 
plot(x1(jj),y1(jj),'wo'); 
hold off 
world(jj,:) = input('Please enter the world coordinates for the white \n circle marked in the current figure (in square parenthesis): '); 
end 
close(fig1); 

你对如何解决这个问题有什么想法吗？

谢谢。

没关系，我用空格键代替Enter，它工作正常。
