How do I fill lines between 2 values with interpolation

Hi all,

I want to interpolate between 2 points and fill an array with the results, without knowing the step between each value. For example, If I have the vector

x=[1;zeros(17,1);10];

and would like to fill all the zeros by a linear regular step.

In Excel, it's like when you select space between 2 points and do Fille-> Series. Excel calculate the step and fill the empty spaces. I would like to do the same with multiple situation like this, this is why I want to use Matlab.

I tried the function interp1, but I'm not able to make it run since it asks for vectors I don't have...

I'm sorry that I can't provide codes... but I don't have anything that come close to a good results..

Thank you in adance!

Probably, the easiest:

startvalue = 1;
endvalue = 10;
numberofpoints = 19; %includes start and end point
x = linspace(startvalue, endvalue, numberofpoints)

Thank you Guillaume! I didn't know about this function! Thanks a lot it works perfectly.
