Perform least squares regression to determine the coefficients a and b ussing the manipulation

solubility with temperature

S = a.exp(bT)

the manipulation ln(S) = ln(a) + bT

See attached pic for the full details. thanx a million !

[jean claude]

look here

T=[77 100 185 239 285]';
S=[2.4 3.4 7 11.1 19.6]'/100 ;
S=log(S);
regression=fitlm(T,S);
atilda=table2array(regression.Coefficients(1,1));
a=exp(atilda);  %a
b=table2array(regression.Coefficients(2,1));  %b
