[Help] syms and file *.txt

I have a file *.txt with its content

q1 q2 q3 q4 q5 q6 q7 q8 q9 q10

Normally, in [command window] i must type

syms q1 q2 q3 q4 q5 q6 q7 q8 q9 q10

to declatation.

But Now i want to use [command window] to read file *.txt and declaration automatically. I only change file *.txt

You could try

vars = regexp( fileread('YourFile.txt'), ' ', 'split');
syms(vars{:});

However, I do not promise that it will work (I cannot test it this evening.) If it does not work, then you will require at least one run-time command evaluation, which is not a good idea.

Have you considered renaming your .txt file as a .m file, adding "syms" to the beginning of the line, and using run() to execute the file as a script?

Does your text file contain other things as well? If so then the fileread() would have to be replaced with code that read just the first line of the file.
