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.

Ran in:
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
