How can I produce a matrix with below condition?

Hi everyone.I need to produce a k×1 matrix that its first element always is 1 and the others return a random number in [0,1].This interval contains 0 and 1 and all values between them.

Something like this may be good enough:

k = 8;

result = [1; rand(k-1,1)]

result = 8×1

1.0000 0.2558 0.8030 0.3604 0.5523 0.6364 0.1631 0.6867
