S = char(X) converts the array X that contains nonnegative integers representing character codes into a MATLAB character array (the first 127 codes are ASCII). The actual characters displayed depends on the character encoding scheme for a given font. The result for any elements of X outside the range from 0 to 65535 is not defined (and may vary from platform to platform). Use DOUBLE to convert a character array into its numeric codes. S = char(C), when C is a cell array of strings, places each element of C into the rows of the character array S. Use CELLSTR to convert back. S = char(T1,T2,T3,..) forms the character array S containing the text strings T1,T2,T3,... as rows. Automatically pads each string with blanks in order to form a valid matrix. Each text parameter, Ti, can itself be a character array. This allows the creation of arbitrarily large character arrays. Empty strings are significant. See also strings, double, cellstr, iscellstr, ischar.

>> help double double Convert to double precision. double(X) returns the double precision value for X. If X is already a double precision array, double has no effect. double is called for the expressions in FOR, IF, and WHILE loops if the expression isn't already double precision. double should be overloaded for all objects where it makes sense to convert it into a double precision value. See also single, datatypes, isfloat, isnumeric.

>> help rats rats Rational output. rats(X,LEN) uses RAT to display rational approximations to the elements of X. The string length for each element is LEN. The default is LEN = 13, which allows 6 elements in 78 spaces. Asterisks are used for elements which can't be printed in the allotted space, but which are not negligible compared to the other elements in X. The same algorithm, with the default LEN, is used internally by MATLAB for FORMAT RAT. Class support for input X: float: double, single See also format, rat.
