Name
LININ Tests whether an algebraic is structurally linear for a given
variable.*
LINSOLVE Solves a system of linear equations.
ΣLIST
Returns the sum of the elements in a list.
∆LIST
Returns the first differences of the elements in a list.
ΠLIST
Returns the product of the elements in a list.
→LIST
Takes n specified objects and returns a list of those
objects.
LIST→ Takes a list of n objects and returns each object
separately, and returns the total number of objects to item.
LN Returns the natural (base e ) logarithm of the argument.*
LNAME Returns the variable names in a symbolic expression.
LNCOLLECT Simplifies an expression by collecting logarithmic terms.
LNP1 Returns ln ( x + 1).*
LOG Returns the common logarithm (base 10) of the
argument.*
Stores LOGFIT in Σ PAR . Subsequent executions of LR
LOGFIT
will use the log curve-fitting model.
