what is this missing to be a solution to problem 1 clc; clear; sigmasf = 14; eps = 0.5; ta1 = 273; ta2 = 305; error = inf; xr = ta1; counter = 0; fx = @(ta) -139.34411 + ((1.575701*10^5)/ta) - ((6.642308*10^7)/ta^2) + ((1.243800*10^10)/ta^3) - ((8.621949*10^11)/ta^4) - log; while abs(error) >= eps previous = xr; if fx(ta1) * fx(xr) <= 0 ta2 = xr; else ta1 = xr; end error = abs(xr - previous); counter = counter + 1; end fprintf('There were %g iterations, and the root is %g ', counter, xr - 273)
