calcDateLicenseExpiry
ライセンスがありません
The most common way to time bar your work is to compare todays date with a time bar.
However it is easy for a user to change the date on their machine to get round this. (You can do this on MATLAB for example).
This solution compares the license expiry date with the latest date that files were changed in a check directory[default: 'c:\windows'].
It's a pain to overide this.
This technique should help you protect your intellectual capital when you distribute your work to clients.
% dteEnd = datenum('30-Jun-2005','dd-mmm-yyyy');
% sclrExpire = calcDateLicenseExpiry(dteEnd);
% if sclrExpire>0,
% txtErr= 'Licence expired please contact xxx.yyyy@address.com';
% uiwait(msgbox(txtErr));
% error(txtErr);
% end
Don't know how to stop MATLAB models from being copied. Look forward to hearing your views.
