delcols Returns the matrix that is matrix A with the columns n1...nk

deleted.

delcols(Mtrx(A),Interval(n1...nk)||n1)

Example:

delcols([[1,2,3],[4,5,6],[7,8,9]],1..1) gives

[[1,3],[4,6],[7,9]]

delrows Returns the matrix that is matrix A with the rows n1...nk

deleted.

delrows(Mtrx(A),Interval(n1..n2)||n1)

Example:

delrows([[1,2,3],[4,5,6],[7,8,9]],1..1) gives

[[1,2,3],[7,8,9]]

deltalist Returns the list of the differences between consecutive terms in

the original list.

deltalist(Lst)

Example:

deltalist([1,4,8,9]) gives [3,4,1]

Dirac Returns the value of the Dirac delta function for a real number.

Dirac(Real)

Example:

Dirac(1) gives 0

division_point Returns a point M such that for the given a and b,

(z–a)=k*(z–b) and z=MA=k*MB.

division_point(Pnt or Cplx(a),Pnt or

Cplx(b),Cplx(k))

Example:

division_point(0,6+6*i,4) returns point (8,8)

DO Used in programming to initiate a step or sequence of steps.

DrawSlp Draws the line with slope m that goes through the point (a,b)

(i.e. y–b=m(x–a)).

DrawSlp(Real(a),Real(b),Real(m))

Example:

DrawSlp(2,1,3) draws the line given by y=3x–5
