我在第 51 行收到一个解析错误(从 startw = input('输入起始波长:') 开始),但我不知道为什么。错误是这样写的;行:51 列:1 此语句不在任何函数内。(它遵循终止函数“OpticalFunction”定义的 END。)当在 Matlab 脚本上运行时,有问题的行本身工作得很好。
function OpticalFunction
daq.reset
clear, close all
clc;
s = daq.createSession('ni');
% Creates the session object
s.addDigitalChannel('Dev1','Port0/Line0:7','OutputOnly');
% Adds 8 digital output channels (numbered 0:7) on the DAQ card
% The following creates the uicontrols
onoff = uicontrol('Style','togglebutton','String','go',...
'Position',[20 200 70 40],'Callback',@move_buggy);
forwards = uicontrol('Style','pushbutton','String','forwards',...
'Position',[20 150 70 40],'Callback',@go_forward);
backwards = uicontrol('Style','pushbutton','String','backwards',...
'Position',[20 100 70 40],'Callback',@go_backward);
nout = [51 102 204 153]; % decimal sequence for forward motion
% This is the callback function for the toggle button.
% It moves the buggy when the toggle button is pressed.
% 'hObject' is the handle for the uicontrol calling the function.
function move_buggy(hObject,eventdata)
while hObject.Value == hObject.Max
for n=1:4
output_data=dec2binvec(nout(n),8);
% high state=1 low state=0
outputSingleScan(s,output_data);
% outputs the data in output_data to the device
pause(1.6)
% use this to change the speed of the motor
end
end
end
% These are the callbacks for the pushbuttons.
% They set the direction of travel for the motors.

nout = [51 102 204 153];
end
function go_backward(hObject,eventdata)
