With the function as given, you can calculate its value for each a in a loop:
Func2 = @(a,b,c) 20*b^2-4*a^6+20+4*c;
a = 0:0.25:10;
b = -3;
c = 8;
vals = zeros(size(a));
for ii = 1:numel(vals)
vals(ii) = Func2(a(ii),b,c);
end
and plot:
plot(a,vals,'.-')
Or you could vectorize the function and calculate its values for all a at once:
Func2 = @(a,b,c) 20*b.^2-4*a.^6+20+4*c; % now any of a,b,c can be a vector (or all of them, if they are the same size)
a = 0:0.25:10;
b = -3;
c = 8;
vals = Func2(a,b,c);
and plot:
plot(a,vals,'.-')
