Hi Team
I am trying to make a text file and store few vector variables in it.
example
a = [1:10]
b = [200:2010]
c= [30:40]
all equal length variables
save ('xyz.txt','a','b','c')
when i do
type xyz.txt
the command window shows me gibberish. All alpha numeric characters and nothing makes sense. How can i store values in text file and read my file for contents without downloading it into an array or any other variable?

I would suggest you to use file opening, writing it and closing it as it is more organised and easily understandable.
fid = fopen('xyz.txt','w');
fprintf(fid, '%s\n',num2str(a),num2str(b),num2str(c));
fclose(fid);

Thank you. My code failed but file identifier method worked: does that mean Txt files cannot be saved as dat files or mat file?

Theoretically you can save txt files using save, but the data will be corrupted and we have to write extra conversions and logics which makes it more complex and is not recommended.
