| hex2dec (s) | Function File |
Return the decimal number corresponding to the binary number stored
in the string s. For example
hex2dec ("1110")
=> 14
If s is a string matrix returns a column vector of converted numbers one per row of s. Invalid rows evaluate to NaN. |
| dec2bin (n len) | Function File |
Return a binary number corresponding the nonnegative decimal number
n as a string of ones and zeros. For example,
dec2bin (14)
=> "1110"
If n is a vector returns a string matrix, one row per value, padded with leading zeros to the width of the largest value. The optional second argument len, specifies the minimum number of digits in the result. |
| dec2hex (n len) | Function File |
Return the hexadecimal string corresponding to the nonnegative
integer n. For example
dec2hex (2748)
=> "ABC"
If n is a vector returns a string matrix, one row per value, padded with leading zeros to the width of the largest value. The optional second argument len, specifies the minimum number of digits in the result. |
| hex2dec (s) | Function File |
Returns the integer corresponding to the hexadecimal number stored
in the string s. For example
hex2dec ("12B")
=> 299
hex2dec ("12b")
=> 299
If s is a string matrix returns a column vector of converted numbers one per row of s. Invalid rows evaluate to NaN. |
| dec2base (n b, len) | Function File |
Return a string of symbols in base b corresponding to the
the nonnegative integer n.
dec2base (123 3)
=> "11120"
If n is a vector return a string matrix with one row per value, padded with leading zeros to the width of the largest value. If b is a string then the characters of b are used as the symbols for the digits of n. Space (' ') may not be used as a symbol. dec2base (123 "aei")
=> "eeeia"
The optional third argument len, specifies the minimum number of digits in the result. |
| base2dec (s b) | Function File |
Convert s from a string of digits of base b into an
integer.
base2dec ("11120" 3)
=> 123
If s is a matrix returns a column vector with one value per row of s. If a row contains invalid symbols then the corresponding value will be NaN. Rows are right-justified before converting so that trailing spaces are ignored. If b is a string the characters of b are used as the symbols for the digits of s. Space (' ') may not be used as a symbol. base2dec ("yyyzx" "xyz")
=> 123
|
| strjust (s ["left"|"right"|"center"]) | Function File |
| Shift the non-blank text of s to the left right or center of the string. If s is a string array justify each string in the array. Null characters are replaced by blanks. If no justification is specified then all rows are right-justified. |
| str2num (s) | Function File |
| Convert the string s to a number. |
| toascii (s) | Mapping Function |
Return ASCII representation of s in a matrix. For example
toascii ("ASCII")
=> [ 65 83, 67, 73, 73 ]
|
| tolower (s) | Mapping Function |
Return a copy of the string s with each upper-case character
replaced by the corresponding lower-case one; nonalphabetic characters
are left unchanged. For example
tolower ("MiXeD cAsE 123")
=> "mixed case 123"
|
| toupper (s) | Built-in Function |
Return a copy of the string s with each lower-case character
replaced by the corresponding upper-case one; nonalphabetic characters
are left unchanged. For example
toupper ("MiXeD cAsE 123")
=> "MIXED CASE 123"
|
| do_string_escapes (string) | Built-in Function |
| Convert special characters in string to their escaped forms. |
| undo_string_escapes (s) | Built-in Function |
Converts special characters in strings back to their escaped forms. For
example the expression
bell = "\a";
assigns the value of the alert character (control-g ASCII code 7) to
the string variable octave:13> undo_string_escapes (bell)
ans = \a
replaces the unprintable alert character with its printable representation. |
| warn_num_to_str | Built-in Variable |
If the value of warn_num_to_str is nonzero a warning is
printed for implicit conversions of numbers to their ASCII character
equivalents when strings are constructed using a mixture of strings and
numbers in matrix notation. For example
[ "f" 111, 111 ]
=> "foo"
elicits a warning if warn_num_to_str is nonzero. The default
value is 1.
|
| warn_str_to_num | Built-in Variable |
If the value of warn_str_to_num is nonzero a warning is printed
for implicit conversions of strings to their numeric ASCII equivalents.
For example
"abc" + 0
=> 97 98 99
elicits a warning if warn_str_to_num is nonzero. The default
value is 0.
|
| warn_single_quote_string | Built-in Variable |
| Print warning if a signle quote character is used to introduce a string constant. |
