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.

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