MATLAB: How to write low level text to a file without interpretation

Question

Hello,

i want to filter a given textfile. Therefore i open a file and make a cell array with the desired lines of text.

Now i want to save the text into a textfile (*.txt).

The given lines are for example:

' -------- Iteration 0 --------'
' Masking 8% (1393) of the nominal rays'
' RMS = 21.6nm, PV = 163.9nm, d_t = 0s'

If i use fprintf, the output looks like this:

 -------- Iteration 0 --------
 Masking 8
 RMS = 21.6nm, PV = 163.9nm, d_t = 0s

This is clearly because matlab interprets the '%'. I didn't check if other chars would be also interpretet by matlab.

I cannot modify the lines to write without investigating massive calculation-time (by checking every single line before writing).

Is there a way to write text low-level to a file without any interpretation?

Thanks

If you want to write a char array, you should use the fprintf('%s', txt) syntax, otherwise fprintf will interpret your input as a format specification. (don't forget to add newline characters as needed, either in the char array itself or with '%s\n')
