Functions and commands 329

Zeros With an expression as argument, returns the zeros (real or

complex according to the mode) of the expression. With a list

of expressions as argument, returns the matrix where the rows

are the solutions of the system (i.e. expression1=0,

expression2=0,...,).

zeros(Expr,[Var])

zeros([LstExpr],[LStVar])

Example:

zeros(x^2+4) gives [] in real mode and [-2*i,2*i]

in complex mode

Complex Solve Returns a list where the elements are complex solutions of the

system of polynomial equations.

csolve(LstEq,LstVar)

Example:

csolve(x^4-1,x) gives list[1,-1,-i,i]

Complex Zeros With an expression as argument, returns the complex zeros of

the expression. With a list of expressions as argument, returns

the matrix where the rows are the solutions of the system (i.e.

expression1=0, expression2=0,...,).

Czeros(Expr,[Var])

Czeros([LstExpr],[LStVar])

Example:

cZeros(x^2-1) gives [1,-1]

Numerical Solve Returns the numerical solution of an equation or a system of

equations.

nSolve(Expr,Var||Var=Guess)

Examples:

nSolve(cos(x)=x,x) gives 0.999847741531

nSolve(cos(x)=x,x=1.3)

gives 0.999847741531
