Help with for loops
显示 更早的评论
Trying to create a program that asks user to input a number (integer) and then generates a list of randomly generated numbers (integers) between ‘1’ and number that user entered. Their should not be any repetition of numbers in the list.
I have this so far and I can't seem to figure out how to not repeat the #'s and to display the inputted integer. I know I have to use a if command but don't know how to execute! I have attempted to use if and else statements but I am stuck.
clc;
x = input('Enter a integer: ');
for x=1:x,
k=round(rand*x);
fprintf('%d\n',k)
end
Any Help is most appreciated.

x = input('Enter your number\n');
randperm(x)

you mean just
randperm(x)'

you can just do
x = input('Enter your number\n');
randperm(x)'

Walter, you should keep your posts in the thread. Why are you trying this?
x = input('Enter a integer: ');
for x=1:x,
k=randperm(x);
fprintf('%d\n',k)
end
Do not do for x=1:x, that is not what I showed you, read the help for randperm() it gives you a random permutation up to x

x = input('Enter a integer:\n');
y = randperm(x);
fprintf('%d\n',y);
Why are you trying to put it in to a for loop?
