zip

Applies a bivariate function to the elements of two lists or vectors and returns the results in a vector. Without

the default value the length of the vector is the minimum of the lengths of the two lists; with the default

value, the shorter list is padded with the default value.

zip(‘function’List1, List2, Default) or zip(‘function’, Vector1, Vector2,

Default)

Example:

zip('+',[a,b,c,d], [1,2,3,4]) returns [a+1 b+2 c+3 d+4]

ztrans

z transform of a sequence.

ztrans(Expr,[Var],[ZtransVar])

Example:

ztrans(a^n,n,z) returns –z/(a-z)

Found in the Catalog menu and the Template menu, the where command has several uses associated with

variable declarations. For one, it is used to substitute values for one or more variables in an expression. It can

also be used to dene the domain of a variable.

Expr|Var=Val or Expr|{Var1=Val1, Var2=Val2…Varn=Valn} or Expr|Var>n or Expr|

Var<n and so on.

Examples:

(X+Y)|{X=2, Y=6} returns 8

int((1-x)^p|p>0,x,0,1) returns ((-x+1)^(p+1))/(-p-1)

Returns the square of an expression.
