SYSEVAL

Type: Command
Description: Evaluate System Object Command: Evaluates unnamed operating system objects specified by
their memory addresses.
WARNING: Use extreme care when executing this function. Using SYSEVAL with
random addresses will almost always cause a memory loss. Do not use this function
unless you know what you are doing.

SYLVESTER

CAS: For symmetric matrix A, return D and P where D is diagonal and A = P

SYST2MAT

CAS: Convert a system of linear equations in algebraic form to matrix form.
%T
Type: Function
Description: Percent of Total Function: Returns the percent of the first argument that is represented by the
second argument.
If both arguments are unit objects, the units must be consistent with each other.
The dimensions of a unit object are dropped from the result, but units are part of the calculation.
For more information on using temperature units with arithmetic functions, refer to the entry for
