sesolve

Finds the root of an equation using a Numerical Technique called Secant Method.

Calling Sequence

c=sesolve(a,b,f,tol)

Arguments

a

Initial Guess(1)

b

Initial Guess(2)

f

equation(function) whose root is to be estimated

tol

Tolerance or acceptable error in the root.

c

root of the equation

Description

Finds the root of an equation using the Numerical technique of Finding a root called Secant Method.

NOTE: This method does not find all the roots but only One root near the initial guesses.

To find different roots try using different initial guesses.

Examples

deff('a=f(x)','a=9*x^3-81');
sesolve(5,25,f,0.00000001)
