Create a function and plot it
显示 更早的评论
Hello I have the following function:
f(x) = 1 + a/ 2.5 + x
a= some value
I would like to plot that function. I try to do it with a loop but it takes a lot of time when my x interval is too large.
for x = 1:1000
a= 500
fx = 1 + (a/ (2.5 + x));
plot(x,fx,'-*', 'color','blue');
hold on;
end
Is there other way to plot the function maybe defining it with the matlab function command?

There are two ways to do this.
[Solution 1]
a = 500;
x = 1:1000;
fx = 1 + (a ./ (2.5 + x));
figure
plot(x,fx)
[Solution 2]
a = 500;
fx = @(x) 1 + (a ./ (2.5 + x));
figure
fplot(fx,[1 1000])
