nCr()

⇒
Value1 Value2
nCr( , )
For integer Value1 and Value2 with Value1
the number of combinations of Value1 things taken Value2 at a time.
(This is also known as a binomial coefficient.)

List1 List2 list
nCr( , )
Returns a list of combinations based on the corresponding element
pairs in the two lists. The arguments must be the same size list.
⇒
Matrix1 Matrix2
nCr( , )
Returns a matrix of combinations based on the corresponding
element pairs in the two matrices. The arguments must be the same
size matrix.

nDeriv()

nDeriv( , [
Expr1 Var H
nDeriv( , [, ] |
Expr1 Var =Value
nDeriv( , [
List1 Var =Value
nDeriv( , [
Matrix1 Var =Value
nDeriv( , [
Returns the numerical derivative as an expression. Uses the central
difference quotient formula.
When Value is specified, it overrides any prior variable assignment or
any current "such that" substitution for the variable.
H is the step value. If H is omitted, it defaults to 0.001.
When using List1 or Matrix1, the operation gets mapped across the
values in the list or across the matrix elements.

newList()

⇒
numElements
newList( )
Returns a list with a dimension of numElements. Each element is
zero.

newMat()

numRows numColumns
newMat( ,
Returns a matrix of zeros with the dimension numRows by
numColumns.
