matlab read string

Hi all,

1) How to read lines of vector from file?
For example,
I have a file:
12 45 78 41 54 78 41 74 57 84
43 54 84 54 78 74 57 12 45 45
41 85 12 45 45 43 54 84 45 78
How to read one line each time?

2) How to read lines of string from file?
For example,
I have a file:
100110101010100101101000110001
101100110110100101120010111010
010100101011000101101010101001
How to read one line each time?

Any suggestions will be appreciated!

Best regards,
Davy
 

matlab read line

Are those ASCII text files?

Read the files into what? Character arrays? Integer arrays?

Is your second example suppose to be binary? Why is there a '2' in there?
 

matlab read line by line

Hi,

They are ASCII files. Read the files into integer arrays.
And the '2' should be '1'.

Thanks!
Davy
 

matlab read file line by line

Still not too clear what you need. What does "one line each time" mean? Maybe show us what the MATLAB arrays should contain after reading the file.

Maybe one of these functions will help: fscanf, dlmread, textread, textscan
 

matlab read vector from file

Hi echo47,

Maybe there is a FOR loop.

For i=1:3
%when i=1
% vector1=[12 45 78 41 54 78 41 74 57 84];
%when i=2
% vector1=[43 54 84 54 78 74 57 12 45 45];
%... ...
%when i=1
% vector2=[1 0 0 1 1 0 1 0 1 0 1 0 1 0 0 1 0 1 1 0 1 0 0 0 1 1 0 0 0 1 ];
%... ...

end

BTW, I like the SAVE, LOAD command. But they seems load the matrix once. And I want to load a line of vector once.

Thanks!
Davy
 

matlab read string from file

Dear davy,
I cannot get what u really want but i think this may help
write in the workspace "lookfor iofun", this will search for all input output functins supported in matlab & among which that supports file reading.
