I have an array 10X1
-7.55
-7.62
-7.59
-7.75
-7.78
-7.69
-7.63
-7.69
-7.58
-7.95
Now, i want to insert values in between two successive values as (-7.585) in between ( -7.55 -7.62) and so on, so that my array become 19X1.

This should get the job done:
data=[-7.55;-7.62;-7.59;-7.75;-7.78;-7.69;-7.63;-7.69;-7.58;-7.95];
newdata=interp1(...
1:numel(data),... create x values
data,... treat the data as y values
1:0.5:numel(data),... create the new x values to sample
'linear'); % force the use of a linear interpolation
disp(newdata)

What exactly do you mean by 'after the 10th value'? Do you want to extrapolate after the array you have? If you want that, you will have to find the pattern in your numbers.
plot(data)
I don't see any pattern. Can you predict what value should be at x=10.5?
