402 Functions and commands

mRow Multiplies the row n1 of the matrix A by an expression.

mRow(Expr,Mtrx(A),Intg(n1))

Example:

mRow(12,[[1,2],[3,4],[5,6]],0) gives

[[12,24],[3,4],[5,6]]

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(1/(3+i*2)) gives 1*(3+(-i)*2)/

((3+(i)*2)*(3+(-i)*2))

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(sqrt(3)-sqrt(2)) gives (sqrt(3)-

(sqrt(2)))*(sqrt(3)+sqrt(2))/

(sqrt(3)+sqrt(2))

nDeriv Returns an approximate value of the derivative of an

expression at a given point, using f’(x)=(f(x+h)–f(x+h))/2*h.

Without a third argument, the value of h is set to 0.001. With

a real as third argument, it is the value of h.

nDeriv(Expr,Var(var),[Real(h)])

Example:

nDeriv(f(x),x,h) gives (f(x+h)-(f(x-h)))*0.5/h

NEG Unary minus. Enters the negative sign.
