Example:
stddevp({1,2,3}) gives 1
sto
Stores a real or string in a variable.
sto((Real or Str),Var)
sturmseq
Returns the Sturm sequence for a polynomial or a rational fraction.
sturmseq(Poly,[Var])
Example:
sturmseq(x^3-1,x) gives [1 [[1 0 0 -1] [3 0 0] 9] 1]
subMat
Extracts from a matrix a sub matrix whose diagonal is dened by four integers. The rst two integers dene
the row and column of the rst element and the last two integers dene the row and column of the last
element of the sub matrix.
subMat(Matrix, Int1, Int2, Int3, Int4)
Example:
subMat returns
suppress
Given a list and an element, deletes the rst occurrence of the element in the list (if there is one) and returns
the result.
suppress(List, Element)
Example:
suppress([0 1 2 3 2],2) returns [0 1 3 2]
surd
Given an expression and an integer n, returns the expression raised to the power 1/n.
surd(Expr, Integer)
Example:
surd(8,3) gives -2
sylvester
Returns the Sylvester matrix of two polynomials.
sylvester(Poly1, Poly2, Var)
