在Matlab中读取值文件

Question

Currently I am using read comma-separated value (CSV) file which is csvread in my code. what if I want to read value row by row, which my value is not seperated by comma?

This is my code for save data:

%% Save data to .txt
fid=fopen('MyFile1.txt','w');
fprintf(fid, '%f \n', AngleValue');
fclose(fid);

This is the save values

Then I run a code using csvread

I = csvread('MyFile1.txt');

but I got an error. can anyone give an idea, probably I should change how I save my data or how can I read the data row by row. Thanks

Answer 1

There are other alternatives to csvread . Try dlmread instead

I = dlmread('MyFile.txt');

A more general approach,
Why are you writing AngleValue as text files? Why not use save and load in a more Matlab-ish fashion? read and write in binary format, tailored for Matlab use?

 save('MyFile.mat','AngleValue'); %// save to binary Mat file

Once you saved the variable, you can read it:

 load('MyFile.mat'); %// that's it!

Answer 2

use

A = fscanf(fileID,formatSpec)

Answer 3

Problem solved. I found out that i just have to put coma (,) when i fprintf my saved data.

My previous code:

fprintf(fid, '%f \n', AngleValue');

My corrected code:

fprintf(fid, '%f,', AngleValue');

So now i can use csvread in my program.
