Hi, i have an array of numbers from 3 to 35 and i have a function created to shuffle these numbers. Right now my program takes the numbers from 3:35 and shuffles them. My question is how do i remove 9 random numbers from this array of shuffled numbers. Thanks

shuffled_data=randi(35,[1 35]); % Just Example
shuffle_data(randi(length(shuffle_data),[1 9]))=[]

thanks, i made an error in my question, to correct myself and to clarify i wanted to just remove 9 values from my shuffled array they don't have to be randomized because theyre already shuffled.

shuffle_data(1:9)=[]
or
shuffle_data(randi(27):randi(27)+9)=[]
or
shuffle_data(end-9:end)=[]

shuffled_data(ismember(shuffled_data, values_to_ignore)) = [];

Since they’re already shuffled simply do vec = vec(10:end) % Remove 9 values
