Strings

Hey guys,

I would like to input a string and then ask matlab to save a series of data with the file name of already input string. e.g. if the string that is input in the starting point of program is analyzed_data1 how can I assign this string in file_name below? Supposedly that there are several save commands, it would help to avoid frequently typing analysed_data1 every time.

save(fullfile(path,'file_name'));

Thank you so much :)

Hi,

you are nearly there, I believe: suppose you write in your program at the top

myfilename = 'analysed_data1';

you just call save with

save(fullfile(path, myfilename));

PS: you might also want to take a look at uigetfile ...

Thanks for your answer, but if you run this:

filename= input('input a file name');

path='D:\...'; %Set a path

a= [1 2 3 4 5;2 3 4 5 4];

save(fullfile(path,filename),'a');

and give a string as a name it doesn't really work!!!

Hi Mehdi,

strange. Works for me, when entering the filename as a string, i.e., when prompted for filename I entered 'foo' (including the two ').

Medhi, you need to use the 's' option on input()

filename = input('input a file name', 's');

It helps if you say specifically the problems you encounter rather than just sayiing "it doesn't really work"

[Titus Edelhofer]

I guess by now the question is obsolete, because Mehdi asked a somewhat similar question with topic "save path" ...

[M G]

I got the problem. You're right. Thanks a lot :)

Depending on your os the slashes could be different. For instance on opensuse I have to use /

path='temp/matlab.mat';
save(path)

With \ it just makes a string and the \'s are just part of the filename. You can make sure to get the correct one by opening the folder and copying the path from there.

Thanks Ivan, your comment helped :)
