Convert fig into csv, txt or ascii

I have the m-file on generating all the graphs in .fig I need with a for loop, but I don't know how to extract the array data to csv, txt or ascii format (16-bit).

    imagesc(x,y,C);  %C is the data I want to extract
    %m and n are variables created inside the for loop

I have tried dlmwrite and save, but I failed and could not fix the problem.

So I want to convert fig into csv, txt or ascii format instead.

    filename_B=strcat(MM,'_profile');  %MM is a variable created inside the for loop
    dlmwrite(filename_B.txt,squeeze(Data_time(:,m,n,:)),'');  %Data_time is C
    save(filename_B, squeeze(Data_time(:,m,n,:)),'-ascii','-double');

It would be better if I could just extract the data directly to the desirable format without first producing fig then convert.

For confidential issue, I can't provide the whole script, but I will try my best to explain my problem.

Many thanks!

I've never used it myself but there is a

doc csvwrite

function that sounds like it does what you want with respect to writing to csv.

doc fprintf

will write to a text file too if you specify it correctly.

thank you!

I have just tried csvwrite, and here's the problem...

csvwrite(filename_B, squeeze(Data_time(:,m,n,:)));
%all the output files are saved as an unknown file type, 
%and the for loop works perfectly,
%but unknown file type is useless

csvwrite(filename_B.txt, squeeze(Data_time(:,m,n,:)));
%after I added the file extension (.txt),
%there is an error message,
%Attempt to reference field of non-structure array.

I don't understand the error message, so I can't fix it.

csvwrite('filename_B.txt', squeeze(Data_time(:,m,n,:)));

or if filenme_B is a string,

csvwrite([filename_B '.txt'], squeeze(Data_time(:,m,n,:)));

csvwrite works perfectly now, thank you everyone!
