I have a txt file here but there is a problem in the X-axis and I have to reduce it by the value 1.4
I did it in Matlab but I failed to save it as new txt file
Here is my attempt:
clear all
X=D398(:,1)-(1.4); Y=D398(:,2);
A=[X Y];
fileID = fopen('NewFile.txt','w');
fprintf(fileID,'%6.2f %12.8f\n',A);
The Y axis in the NewFile is not the same as before!

generally speaking arrays in MATLAB are stored in a column major fashion. In this case matrix A is first converted columnwise into a vector and then its components are sequentially written out to file.
To get the desirable outcome, the following line of code needs to be instead used,
fprintf(fileID,'%6.2f %12.8f\n',A.');
Kind Regards,
