Regula Falsi or False Position Method Pseudocode
False position method is bracketing method for finding real root of non-linear equations. This article covers pseudocode for False Position method for finding real root of a given function. False position method is also known as Regula-Falsi method.
Pseudocode for False Position Method
1. Start 2. Define function f(x) 3. Input a. Lower and Upper guesses x0 and x1 b. tolerable error e 4. If f(x0)*f(x1) > 0 print "Incorrect initial guesses" goto 3 End If 5. Do x2 = x0 - ((x0-x1) * f(x0))/(f(x0) - f(x1)) If f(x0)*f(x2) < 0 x1 = x2 Else x0 = x2 End If While abs(f(x2) > e 6. Print root as x2 7. Stop
