I would like to save all simulation variables ad fig with the current time.
my solution:
t = datetime('now','Format','dd-MM-yyyy''_T''HHmmss');
t2 = datevec(t);
DateString = datestr(t2);
filename=[DateString,' all_variables_main '];
save(filename )
savefig(filename)
The following error was given in Matlab:
Unable to write file 26-Oct-2019 09:47:15 all_variables_main : Invalid argument.
What have I done wrong?
File name containing : character is not a valid file name.
You can replace the : with "꞉" character.
See: How to get a file in Windows with a colon in the filename?
You can replace all : with ꞉ character (unicode character A789 that looks like colon) that is valid to be used in file name.
filename(filename == ':') = char(hex2dec('A789'));
Make sure to use the right character when loading the file.
Remark: The above solution was tested in Windows 10, and MATLAB R2016a.
mat filenames cannot have spaces or colons in them. You can use the following to directly obtain the date and time in a format that is allowed in a filename:
>> fileName = [datestr(now, 'dd-mmm-yyyy_HHMMSS') '_all_variables_main']
fileName =
'26-Oct-2019_103123_all_variables_main'
>> save(fileName)
