Description
|
|
|
•
|
The makeparam and makeglobal functions are used to make a variable to be a parameter, respectively global variable in the Maple procedure. If a list of variables is given, then all the variables in the list are made into parameters, respectively globals.
|
|
•
|
If a type t is specified the variable is given the specified type. This can be used to declare the type of a variable.
|
|
•
|
The declare function is used to specify the type t for a variable x which is a parameter in the Maple procedure f.
