Functions and commands 175

> Strict greater than inequality test. Returns 1 if the left side of

the inequality is greater than the right side, and 0 otherwise.

Note that more than two objects can be compared. See

comment above regarding <.

>= Greater than or equal inequality test. Returns 1 if the left side

of the inequality is greater than the right side or if the two

sides are equal, and 0 otherwise. Note that more than two

objects can be compared. See comment above regarding <.

^ Power symbol. Raises a number to a power or a matrix to an

integer power.

a2q Given a symmetric matrix and a vector of variables, returns

the quadratic form of the matrix using the variables in the

vector.

a2q(Matrix, [Var1, Var2….])

Example:

a2q([[1,2],[4,4]],[x,y]) returns x^2+6*x*y+4*y^2

abcuv Given three polynomials A, B, and C, returns U and V such

that A*U+B*V=C. With a variable as the final argument, U

and V are expressed in terms of that variable (if needed);

otherwise, x is used.

abcuv(PolyA, PolyB, PolyC, [Var])

Example:

abcuv(x^2+2*x+1,x^2-1,x+1) returns [1/2 -1/2]

additionally Used in programming with assume to state an additional

assumption about a variable.

Example:

assume(n,integer);

additionally(n>5);

algvar Returns the matrix of the symbolic variable names used in an

expression. The list is ordered by the algebraic extensions

required to build the original expression.

algvar(Expr)

Example:

algvar(sqrt(x)+y) gives

1 2 ... 174 175 176 177 178 179 180 181 182 183 184 ... 333 334
