3057 escape sequences within single quoted strings.\n\

3059 Ordinarily, escape sequences such as \"\\n\" => newline are only processed\n\
3060 in double quoted strings. However, @sc{matlab} performs escape sequence\n\
3061 processing even for single quoted strings for certain functions. This\n\
3062 variable enables @sc{matlab} compatibility for these instances:\n\

3081 When called from inside a function with the \"local\" option, the variable is\n\
