N nCr( ) nCr(Value1, Value2) ⇒ expression For integer Value1 and Value2 with Value1 , Value2 , 0, nCr() is the number of combinations of Value1 things taken Value2 at a time. (This is also known as a binomial coefficient.) nCr(Value, 0) ⇒ 1 nCr(Value, negInteger) ⇒ 0 nCr(Value, posInteger) ⇒ Value·(ValueN1)... (ValueNposInteger+1)/ posInteger! nCr(Value, nonInteger) ⇒ expression!/ ((ValueNnonInteger)!·nonInteger!) nCr(List1, List2) ⇒ list Returns a list of combinations based on the corresponding element pairs in the two lists. The arguments must be the same size list. nCr(Matrix1, Matrix2) ⇒ matrix 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[=Value] [, H]) ⇒ expression nDeriv(Expr1, Var[, H] | Var=Value) ⇒ expression nDeriv(Expr1, Var[=Value], List) ⇒ list nDeriv(List1, Var[=Value] [, H]) ⇒ list nDeriv(Matrix1, Var[=Value] [, H]) ⇒ matrix 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. Note: See also avgRC(). newList( ) newList(numElements) ⇒ list Returns a list with a dimension of numElements. Each element is zero. newMat( ) newMat(numRows, numColumns) ⇒ matrix Returns a matrix of zeros with the dimension numRows by numColumns.
