items of the above nature, solves the system of recurrent

sequences.

seqsolve(Expr, Vector, Condition) or

seqsolve(List1, List2, List3)

Example:

seqsolve(2x+n,[x,n],1) gives -n-1+2*2

shift_phase Returns the result of applying a phase shift of pi/2 to a

trigonometric expression.

shift_phase(Expr)

Example:

shift_phase(sin(x)) gives -cos((pi+2*x)/2)

signature Returns the signature of a permutation.

signature(Vector)

Example:

signature([2 1 4 5 3]) returns –1

simult Returns the solution to a system of linear equations or several

systems of linear equations presented in matrix form. In the

case of one system of linear equations, takes a matrix of

coefficients and a column matrix of constants, and returns the

column matrix of the solution.

simult(Matrix1, Matrix2)

Example:

simult returns

sincos Returns an expression with the complex exponentials rewritten

in terms of sin and cos.

sincos(Expr)

Example:

sincos(exp(i*x)) gives cos(x)+(i)*sin(x)
