How i can plot the below sigmoid function?

p=2;%Gradient coefficent

z=[0:0.1:1/2]*1e-3;

G=1-1/2*(((h/2)-z)/(h/2)).^p; Sigmoid fuction

z1=[-1/2:0.1:0]*1e-3;

G1=1/2*(((h/2)+z)/(h/2)).^p; Sigmoid function

How i can plot the sigmoid function in the all thickness [-1/2:1/2] ?

p=2;%Gradient coefficent

z=[0:0.1:1/2]*1e-3;

G=1-1/2*(((h/2)-z)/(h/2)).^p; Sigmoid fuction

z1=[-1/2:0.1:0]*1e-3;

G1=1/2*(((h/2)+z)/(h/2)).^p; Sigmoid function

Hi,

I am trying to plot the below sigmoid function versus all thickness.

Any help on how to do that?

Thanks.

It is all about specific parameter values ​​how we know this, because we cannot be from the same subjective field.

• Define the typical values parameter.
• Expression or equation must be correct.

Here I have shown how you can obtain such a plot, but note that, to get exactly the same plot, the parameter values ​​and expressions must be the same according to the literature.

p=1:10; %P data is OK 
h=4;
z=-0.2:0.01:0.2;
for i=1:length(p)
G=1-1/2*(((h/2)-z)/(h/2)).^p(i); 
plot(z./h,G);
hold on
grid on;
end  

Please do modify accordingly, more note on x data, which is z/h

Thanks for your reply.

I can do this expression easily, i work with Matlab for years.

But the expression of G is different in [-1/2:0] interval, G=1/2*(((h/2)+z)/(h/2)).^p(i);

i would like to plot the two different functions in same graph.

%sigmoid distributions,
clear ,
close all
h=1e-3;
p=2;
z=[0:0.1:1/2]*1e-3;
G=1-1/2*(((h/2)-z)/(h/2)).^p;
 
z1=[-1/2:0.1:0]*1e-3;
G1=1/2*(((h/2)+z)/(h/2)).^p;
