lgcd Returns the greatest common divisor of a list of integers or
polynomials.
lgcd(Seq or Lst)
Example:
lgcd([45,75,20,15])
gives
5
lin Returns an expression with the exponentials linearized.
lin(Expr)
Example:
lin((exp(x)^3+exp(x))^2)
gives
exp(6*x)+2*exp(4*x)+exp(2*x)
line_segments Returns the list of the line segments (one line=one segment) of
a polyhedron.
line_segments(Polygon or Polyedr(P))
linear_interpolate Takes a regular sample from a polygonal line defined by a
matrix of two rows.
linear_interpolate(Mtrx,xmin,xmax,xstep)
linear_regression Returns the coefficients a and b of y=a*x+b, where y is the
line that best approximates the points whose coordinates are
the elements in two lists or the rows of a matrix.
linear_regression(Lst||Mtrx(A),[Lst])
Example:
linear_regression([[0.0,0.0],[1.0,1.0],[2.0,4
.0],[3.0,9.0],[4.0,16.0]])
gives
4.0,-2.0
LineHorz Draws the horizontal line y=a.
LineHorz(Expr(a))
LineTan Draws the tangent to y=f(x) at x=a.
LineTan(Expr(f(x)),[Var],Expr(a))
LineVert Draws the vertical line x=a.
LineVert(Expr(a))
