Example 5.7 User defined library of MuPAD procedures

In order to understand what is going on in this example you should read the appropriate fragment of the book. The idea is to write a number of constants, functions and procedures and save them as a MuPAD "library" that can be later used through the read command.

// declarations of constants and functions

MyPI := 3.14;

MyE := 2.72;

MyExp := x -> MyE^x;

// declarations of procedures 

average := proc()

local n, i, result;

begin

   n := args(0);

   result := 0;

   for i from 1 to n do

      result := result + args(i)

   end;

   result := result/n;

 return(result)

end: 

squares := proc()

local n, i, result;

begin

   n:=args(0);

   result := 0;

   for i from 1 to n do

      result := result + args(i)^2

   end;

   return(result)

end:

// first make the folder "userlib" in MuPAD main folder 

WRITEPATH := "userlib"; 

write(Text,"myfunctions.mu")

// library can now be read and used

READPATH := "userlib";

read("myfunctions.mu")
