Need Help to Plot confidence Interval For the following Code

Give range value as per your approximation

%x=[-0.5 -0.4 -0.3 -0.2 -0.1 0 0.1 0.2 0.3 0.4 0.5]'; x=[-0.5 -0.4 -0.3 -0.2 -0.1]';

y=[-2.2026 -0.2981 -0.0403 -0.0055 -0.0007]';

fun = fittype(@(A, B, C, x)(A.*(exp(B.*x)-exp(-C.*x))));

[fitobject,gof,output] = fit(x, y, fun) ABC = coeffvalues(res)
