frprintf into a file with adding the symbol for Single quote

Hello Everyone,

I have a textfile, which I created with matlab. Later, I want to use the text-file with a schme-macro in a simulation programm. I need every line in the textfile like this:

(define bla '(0 0 0 1 1 1)). The zeros and ones represent different possibilites.

My poroblem so far is, that I can't frpint the symbol ', due to the fact, that this symbol marks for matlab the end of the text in my code.

I am that far:

fid1 = fopen('test1.txt');
   fid2 = fopen('test2.txt','w');
   tline = fgets(fid1);
   Character2add = '(define pyrx ('; % here put the character to be added
   while ischar(tline)
      disp(tline)
      fprintf(fid2,'%s %s\n',Character2add,tline);
      tline = fgets(fid1);
   end
fclose(test1);
fclose(test);

What I got with this is:

'(define bla ('0    0    0    1    1    1

What I need now is:

• I need the last 2 paranthesis at the end of each line
• I need the single-quote symbol ' after my bla

fprintf('There''s two main ways to print a single quote')

There's two main ways to print a single quote

fprintf('Two single quotes '''' in a char format specifier prints a single quote '' in the result')

Two single quotes '' in a char format specifier prints a single quote ' in the result

fprintf("Or if you're using a release that supports string, specify the format as a string")

Or if you're using a release that supports string, specify the format as a string

Third way: use a %c or %s format specifier and pass in char(39) or char(0x27)

Fourth way: use a %c format and pass in 39 or 0x27

[Stephen23]

Fifth way: write \x27 directly into the format string

Sixth way: write \47 directly into the format string

Seventh:

fprintf('There are several apostrophes in Unicode:\n39: %c\n700: %c\n1370: %c\nand probably more',39,700,1370)

There are several apostrophes in Unicode:
39: '
700: ʼ
1370: ՚
and probably more
