i want to calculate the average of two values data that side by side and placed it between those two values after that, the last values data will be divided by 2 and placed at the end of the array
for example, if i have
A=[4 2 8 10 6]
then the average of those data that side by side is [3 5 9 8]
after that, the last values of A (=6) will be divided by 2 and equal 3
then i want it to become
B=[4
3
2
5
8
9
10
8
6
3]

Use interp1
A=[4 2 8 10 6];
x = 1:length(A); % 1 2 3 4 5
xx = linspace(x(1),x(end),length(A)*2-1); % 1 1.5 2 2.5 3 3.5 4 4.5 5
A1 = interp1(x,A,xx);
plot(x,A,'.-r')
hold on
plot(xx,A1,'ob')
hold off
A1(end+1) = A1(end)/2; % just divide last element
