what does [^\n\r]' mean?

hi there, i have a sutpi question.. at the and of the string cpnversion specifiers of the matlab implemented import file function there is [^\n\r]. New line and carriage return is clear to me, but what the '^'means?..

formatSpec = '%s%s%s%s%f%f%f%s%s%s%[^\n\r]';

thanks in advance

"^" is a negation. %[^\r\n] matches everything but line break, i.e. the rest of the line. Doc says

    Exclude characters inside the brackets, reading until the first matching
    character.

thanks a lot!, now it is clearer.And I thought just '~' stands for negation.

[per isakson]

"~" is shorthand for the logical function not. (IMO: Use not, it makes the code more readable.) [^\r\n] is a loan from regular expression.

thanks!, I changed to 'not' .
