[Walter Roberson]

for K = 1 : 5
    out(randi(10)) = "entry #" + K;
end

out

out = 1×7 string array
    "entry #4"    <missing>    "entry #5"    "entry #1"    <missing>    "entry #2"    "entry #3"

Beg your Pardon, but I am confused with the instruction if loop runs for 5 times why it creates 1x7 string array?
