i want to translate this vector to a formal syntax that i can use always

clc 
clear all

n=4;
t=0.25;
h=n*t   

for i=1:n+1
    
    if i==1
        k(i)=-h/2;
    else 
        k(i)=-h/2+(i-1)*t;
        
    end
end
b=[k(2)-k(1) k(3)-k(2) k(4)-k(3) k(5)-k(4)];

the code works fine, howvever i want to obtain vector b with using the right syntax. Meaning that i want to write it as a syntax form that will give me same results that vector b gives me (without manualy plotting the values of k everytime).

Answer 1

b=repelem(t,n)

[Mahmoud Chawki]

thank you,

it worked,

how did you directly notice that the asnwer will be always equal to the thickness?

[Matt J]

Because k(i) is a linear function of i with slope t,

 k(i)=-h/2+(i-1)*t;

wow quick thinking great job.
