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 n
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)
