it is better we see it directly.

i want thelast data is n1 n2 n3 n4 so i can make plot directly. recently i did it manually one by one.

thx

I am closing this question until the OP adds details.

the detail:

my problem is its iteration. manually it is ok. but i have many plots ánd datas.

i have a figure that have many plots within.

i want:

(y3-y2)/(y2-y1)=n1

(y4-y3)/(y3-y2)=n2

(y5-y4)/(y4-y3)=n3

(y6-y5)/(y5-y4)=n4

and soon until n7

the function of the figure is

w=8;

x=2;

a=0.2;

w=(0:0.3:3);

k=1; 1, 2,3,4,5,6,7 ; variable change

S=[1-exp(-a.*x.*k.*w)];

figure(1)

plot(w,S,'-+');

xlabel('w');

ylabel('S');

hold on

if we run this with k= 1, 2,3,4,5,6,7 we will find plots at one figure. and i want to calculate n1..n7 as above.
