Incremental conditions for if statement

I'm trying to return an invalid message for any value not inside the parameters.

Given this for loop with an embedded while and if just to check the inputs value.

for i = 1:2

fprintf("iteration %d\n", i);

flag = 1;

while flag == 1

row = input(":");

if row ~= 1

fprintf("invalid input\n");

fprintf("while restarts\n");

flag = 1;

else

fprintf("valid input\n");

flag = 0;

end

end

fprintf("while ends\n");

end

fprintf("end\n");

Is there a way to implement a if row ~= 1:10 condition?

Alternativley is there a way to use switch cases?

Obviously switch case can be used to display valid for 1:10 but it will break the code if any other input is entered.

If you want to check if a number is not in a given set, use ismember.

x = 1:10;
if ismember(5, x)
    disp("5 is in x")
else
    disp("5 is not in x")
end

5 is in x

if ismember(pi, x)
    disp("pi is in x")
else
    disp("pi is not in x")
end

pi is not in x
