HP Prime Graphing NW280AAABA manual Lvar Returns a list of variables used in an expression

logistic_ Returns y, y', C, y'max, xmax, and R, where y is a logistic regression function (the solution of y'/y=a*y+b), such that y(x0)=y0 and

where [y'(x0),y'(x0+1)...] is the best approximation of the line formed by the elements in the list L.

logistic_regression(Lst(L),Real(x0),Real(y0))

Example:

logistic_regression([0.0,1.0,2.0,3.0,4.0],0.0 ,1.0) gives [-17.77/(1+exp(- 0.496893925384*x+2.82232341488+3.14159265359* i)),-2.48542227469/(1+cosh(- 0.496893925384*x+2.82232341488+3.14159265359* i))]

lvar Returns a list of variables used in an expression.

lvar(Expr)

Example:

lvar(exp(x)*2*sin(y)) gives [exp(x),sin(y)]

magenta Used in the Symbolic view of the Geometry app. In the definition of a geometric object, including the statement “display=magenta” specifies that the object defined will be drawn in magenta.

map Applies a function to the elements of the list.

map(List, Function)

Example:

map([1,2,3],x→x^3) gives [1,8,27]

mat2list Returns a list containing the elements of a matrix.

mat2list(Matrix)

Example:

mat2list([[1,8],[4,9]]) gives [1,8,4,9]

matpow Given a matrix and an integer n, returns the nth power of the matrix by jordanization.

matpow(Matrix, Integer)
