Is this the "string function" ?
StrFunc = 'x.^2+2*b+c';
%Converting to a function handle
Letters = unique(regexp(StrFunc, '[a-zA-Z]+', 'match')); %Extract the letters
VarPat = ['@(' sprintf('%s,', Letters{1:end-1}) Letters{end} ')']; %'@(a,b,x)'
Func = str2func([VarPat StrFunc]); % @(b, c, x) x.^2+2*b+c
x = 1:10;
b = 3;
c = 5;
plot(x, Func(b, c, x));
