Trying to graph a 3 variable probability function
显示 更早的评论
So I'm trying to Maximize f(x), for f(x) = 1/(3.5a+2.5b+3c+1)
but I'm not interested in the ''trivial'' solutions where a, b or c = 0 etc.. I'm looking for a visual representation to see the maximums
0 < a < 1
0 < b < 1
0 < c < 1
I've tried to create a matrix with 3 columns of probabilites for a,b,c but it seems it will only calculate the f(x) for a=b=c which is quite annoying tbh, does someone know how to do this please...im going crazy over here.. i've also tried meshgrid, surf and other functions but nothing is working...

Use isosurface to visualize
[a,b,c] = meshgrid(0:0.1:2);
f = 1./(3.5*a+2.5*b+3*c+1);
cla
hold on
for fk = 0 :0.1:1
isosurface(a,b,c,f,fk)
end
hold off
