How to use fprintf with two arrays?

Hi! I'm trying to coalesce two arrays (X and Y) into a text file ('XYresults.txt'). The arrays are both 643x1 and I am trying to get X as the right column, and Y as the left. This is what I have written,

fileID = fopen('XYresults.txt','w');
fprintf(fileID,'%1s %2s\n','X data','Y data');
fprintf(fileID,'%1d %2d\n','X','Y');
fclose(fileID);

but when I run the code and open XYresults.txt, the only results are:

X data Y data
88 89

Does anyone have any advice as to why more data isn't being written? Thank you!

Assuming that X and Y are variables in your workspace, you need

fprintf(fileID,'%1d %2d\n',X,Y);

rather than

fprintf(fileID,'%1d %2d\n','X','Y');

Your code is writing the ASCII values of the characters 'X' and 'Y'.

I was actually able to fix it with the following:

coal = [X,Y];

and

fprintf(fileID,'%6.f %12.f\n',coal);

Makes sense. The main thing is using the variables as input to fprintf, not strings with the variable names.

And obviously

fprintf(fileID,'%1s %2s\n','X data','Y data');

can/should be

fprintf(fileID,'X data, Y data\n');

That's not necessarily obvious for folks who aren't used to the syntax, thank you.
