Adding number to an array

Hello

I have an array r1 = [0.1 0.2 0.3 0.4 0.6 0.7 0.8 0.9]. I want to insert the variable c into this array. c =1

So at the end, the array should become

r1 = [0.1 0.2 0.3 0.4 0.6 0.7 0.8 0.9 1]..

or if c = 0.5, then array becomes

r1 = [0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9].

I want to insert the value c into the array r1.

I looked up this link

https://uk.mathworks.com/help/matlab/math/creating-and-concatenating-matrices.html#OverviewCreatingAndConcatenatingExample-3

but concatenating is not working for me.

Does any one know
