I have a function called CMDEntryExitSuperColoc, with a file path string as input.
In the 1st attempt, I could run this function immediately as a new instance of Matlab by input following into command window:
%%%%%%%%%%
system('matlab -r CMDEntryExitSuperColoc(''D:\QMDownload\SuperColocParaImport1.txt'')')
%%%%%%%%%%
In a 2nd attempt, I need automatically restart computer and run this function by SchTasks. I do it as follows:
%%%%%%%%%%
taskname = 'SuperColocRescue';
runfile = ['C:\Program Files\MATLAB\R2016a\bin\matlab.exe -nosplash -nodesktop -minimize -r CMDEntryExitSuperColoc(''D:\QMDownload\SuperColocParaImport1.txt'')'];
frequency = 'ONCE';
starttime = '21:45';
system(['schtasks /create /tn "',taskname,'" /tr "',runfile,'" /sc ',frequency,' /st ',starttime,' /f']);
!shutdown /f /r /t 1
%%%%%%%%%%
This is what I got:
%%%%%%%%%%

CMDEntryExitSuperColoc(D:\QMDownload\SuperColocParaImport1.txt)
|
Error: Unexpected MATLAB operator.
%%%%%%%%%%
It seems that the ' in the system('matlab... command works, and the function execute directly and siilently without the explicit command information showing on scrren, But the system(['schtasks... commands has a additional interpration procedure as indicated by the explicit CMDEntryExitSuperColoc(D:\QMDownload\SuperColocParaImport1.txt) in the command windows once initialized. However, the ' was lost, and it is no longer a string.
Dose the ' loss caused by Matlab or Windows Task scheduler?
Is there a smart way to input strings without the use of ' with system(['schtasks... command?
Just now I come up with an idea. Convert the path string to numbers, and use,this number as input to avoid ' useage. Then inside the function convert back to string. How to do it？

I have '' '' in the last second lines, so the blank is not worry. Earlier if I do not have '', its exactly what you say. Next I may generate a bat or vbs and schedule it instead.

Solved by using the ASCII number matrix as input: such as CMDEntryExitSuperColoc([23,54,76,98,23,46,68,89,23])
mfileFolderMat = uint8(mfileFolder);
mfileFolderAscListStr = '';
for i = 1 : length(mfileFolderMat)
mfileFolderAscListStr = [mfileFolderAscListStr,num2str(mfileFolderMat(i)),','];
end
mfileFolderAscListStr(end) = '';
mfileFolderAscListStr = ['[',mfileFolderAscListStr,']'];
runfile = ['C:\Program Files\MATLAB\R2016a\bin\matlab.exe -nosplash -nodesktop -minimize -r CMDEntryExitSuperColoc(',mfileFolderAscListStr,')'];
function CMDEntryExitSuperColoc(mfileFolder)
if ~nargin
paraFolder = uigetdir('','Choose a folder containing only your parameter text files');
else
if ischar(mfileFolder)
paraFolder = mfileFolder;
elseif isnumeric(mfileFolder)
paraFolder = char(mfileFolder);
end
end
...
end

system('matlab -r CMDEntryExitSuperColoc(''''D:\QMDownload\SuperColocParaImport1.txt'''')')

As I said,
system('matlab...
already works.
The loss of ' only take place for:
system(['schtasks....
And even for
system(['schtasks...,
I tried double the '','''', they just do not work.
No matter hoe many ' you use, all of them will be lost after schtasks.
