How to make a iteration table for while loof (Solving equations in one variable: false position method)

Hello

I want to make a iteration table for c In this while loof

How can I make a code? It is for solving equations in one variable: false position method

I want to know about convergenc history(table)

x = linspace(-0.5,5,501);

y = -2*exp(x./2) + 10;

a = 2.5;

b = 4;

e = 1*10^-6;

fa = -2*exp(a./2) + 10;

fb = -2*exp(b./2) + 10;

while true

c = (a*fb - b*fa)./(fb - fa); %false position

fc = -2*exp(c./2) + 10;

if fa*fc < 0

b = c;

fb =-2*exp(b./2) + 10;

else

a = c;

fa = -2*exp(a./2) + 10;

end

if abs(fc) < e

break;

end

disp(c);
