about location and input
显示 更早的评论
Hi everyone.
What does this mean?
input = import3struct(location)
I couldn't understand the rule of "locaion" here.

It is a variable.
Have you done a basic Matlab tutorial?

import3struct is either a variable or a function.
If it's a variable, "location" is likely indices used to select parts of the variable.
If it's a function, you could look into that function to determine what the first input is supposed to do.
It's the same as asking what "a" means here: b=f(a). No one could answer that without knowing what f and a are. Before you tell us what f and a are, what's your guess based on this advice?

Is the input a binary file?

So the function import3struct reads some structure from the binary file from location (offset) given by "location".

location is a variable. it should be set as zero at the begining. The program will change it to read more data from the file

Can I see the code for this function ? import3struct
Why did you remove much of your question? I could only recover this from Google cache:

And your last comment:
So I just set input file and the program will work.
This is a part of code:
function dipole_solid_fourier(location,orbital_no)
input = import3struct(location);
fig_ending = '.pdf';
adach_str = sprintf('%1.5f',input.adach);
%FILE_NAME = [location,'/dipolesup.dat'];
FILE_NAME = [location,'/currentsup.dat'];

So, the location is path to the folder containing the data file, for example : location = 'c:/dipole_tess';
FILE_NAME will be the absolute location of the data file. In Windows system you should use '/' instead of '\'

In Windows system you should use '/' instead of '\'
"instead of" implies that on non-Windows systems that you should use '\' . However, Windows is the only OS that MATLAB runs on that permits using '\' as the directory separator, so you should not use '\' on Mac or Linux.
Perhaps you mean that on Windows systems you should use '\' instead of '/' . However, '/' is what Windows uses internally, and changes it to '\' for presentation. You can use either one on Windows. People who use Windows all the time are probably more familiar with using '\' than '/' as the directory separator. I would point out that if you use '/' then you are compatible with all three OS versions. If you want to be compatible with all three and you want to use the separator that is familiar to the user, then use fullfile() instead of using either one.

Yes I meant using '\' instead of '/' in Windows. Fortunately, even in Windows systems, we can uses '/' in Matlab to address the location of a file

Also see f = filesep

function dipole_solid_fourier(location,orbital_no)
input = import3struct(location);
fig_ending = '.pdf';
adach_str = sprintf('%1.5f',input.adach);
%FILE_NAME = [location,'/dipolesup.dat'];
FILE_NAME = [location,'/currentsup.dat'];
Notice that in that final line, location has a character vector appended to it. location is very likely to be a character vector itself. In particular, it is a character vector representing a directory name. The file currentsup.dat will be looked for in the given directory.
