Full Command and Function Reference 3-209
Description: Z Volume Coordinates Command: Sets the height of the view volume in the reserved variable
VPAR.
x
low
and x
high
are real numbers that set the z-coordinates for the view volume used in 3D plots.
These values are stored in the reserved variable VPAR.
Access: …µ

^ (Power)
Type: Function
Description: Power Analytic Function: Returns the value of the level 2 object raised to the power of the level
1 object. This can also apply to a square matrix raised to a whole-number power.
If either argument is complex, the result is complex.
The branch cuts and inverse relations for w
z
are determined by this relationship:
w
z
= exp(z(ln w))
Access: Q
Flags: Principal Solution (-1), Numerical Results (-3)

| (Where)
Type: Function
Description: Where Function: Substitutes values for names in an expression.
| is used primarily in algebraic objects, where its syntax is:
'symb
old
| (name
1
= symb
1
, name
2
= symb
2
…)'
It enables algebraics to include variable-like substitution information about names. Symbolic
functions that delay name evaluation (such as ∫ and ∂) can then extract substitution information
from local variables and include that information in the expression, avoiding the problem that
would occur if the local variables no longer existed when the local names were finally evaluated.
Access: @¦ (¦is the right-shift of the Ikey).
Flags: Numerical Results (-3)
Input/Output:
