402 Functions and commands

modgcd Uses the modular algorithm to return the greatest common

divisor of two polynomials.

modgcd(Poly1,Poly2)

Example:

modgcd(x^4-1,(x-1)^2) gives x-1

mRow Given an expression, a matrix, and an integer n, multiplies

row n of the matrix by the expression.

mRow(Expr, Matrix, Integer)

Example:

mRow returns

mult_c_conjugate If the given complex expression has a complex denominator,

returns the expression after both the numerator and the

denominator have been multiplied by the complex conjugate

of the denominator. If the given complex expression does not

have a complex denominator, returns the expression after

both the numerator and the denominator have been

multiplied by the complex conjugate of the numerator.

mult_c_conjugate(Expr)

Example:

mult_c_conjugate returns

mult_conjugate Takes an expression in which the numerator or the

denominator contains a square root. If the denominator

contains a square root, returns the expression after both the

numerator and the denominator have been multiplied by the

complex conjugate of the denominator. If the denominator

does not contain a square root, returns the expression after

both the numerator and the denominator have been

multiplied by the complex conjugate of the numerator.

mult_conjugate(Expr)

Example:

mult_conjugate returns
