ParseToFunction( <Text> )

Parses the text containing the function definition and creates the corresponding function.

Examples:

ParseToFunction( <Function>, <Text> ): Parses the string and stores the result to a function f, which must be defined and free before the command is used.; Example: Define f(x) = 3x² + 2 and text1 = "f(x) = 3x + 1". ParseToFunction(f, text1) returns f(x) = 3x + 1.

ParseToFunction( <Text>, <List of variables> ): Parses the text containing the function definition and creates the corresponding function of the variables defined in the list.; Example: ParseToFunction("2u+3v",{"u", "v"}) creates the function a(u,v) = 2u + 3v.

Note: See also ParseToNumber command.
