Trying to pull intermittent errors from an array

Within column 8 in each Table_A there are intermittent values of 1, i need to pull the all of the columns of the rows where column 8 is equal to one in each run as they represent a data error in a previous loop that needs to be accounted for in each value of i, these errors should not be more than 200.

I was thinking I could some how fill a zero array with as many rows as neccesary and then leave the rest as zeros?

num = 16; %Number that needs to remain changeable 
goal = 10000; %Number that needs to remain changeable 
Array_A = rand(goal*num,9); %Is built in a previous loop
Errors = zeros(200,num); %Place holder? 
for i = 1:num
    Array_AB = Array_A(i:num:end,:);
    Array_AC = Array_AB(any(Array_AB(:,5:7),2),:);
    Table_A = array2table(Array_AC);
    Table_AB = sortrows(Table_A,[2 3],"descend")
    Errors(:,i) = Array_AC((Array_AC(:,8)==1),:) %Returns an error because dimensions don't match
end

Or perhaps pull the rows i want an pad them?

num = 16 %Number that needs to remain changeable 
goal = 10000 %Number that needs to remain changeable 
Array_A = randi(goal*num,9) %Is built in a previous loop
Errors = zeros(200,num) %Place holder? 
for i = 1:num
    Array_A = A(i:num:end,:); 
    Array_A = Array_A(any(Array_A(:.5:7),2),:);
    Table_A = array2table(Array_A);
    Table_A = sortrows(Table_A,[2 3],"descend")
    Pull = Array_A((Array_A(:,8)==1),:)
    %some magick that turns this into a 200x8 matrix padded with zeros
    Errors(:,i) = Pull
end

Eventually I need Errors to contain the entire row of the runs that contained errors for further analysis.

Sorry, I know this might be confusing, if there's any way i can clarify, please let me know.

Your code is indeed very confusing. There's certainly no explanation why you're first sampling your Array_A every row, then every two rows, then ..., then every 16 rows. It's also unclear why you convert the array to a table. As far as I can tell you don't use any table feature. And finally, why are you sorting the array (repeatedly, at that)?

i need to pull the all of the columns of the rows where column 8 is equal to one ...

That's easily done:

filteredarray = youraray(yourarray(:, 8) == 1);

... in each run

What's a run?

1. I'm sorting Array_A based upon the number of different inputs put in in another section of code, and I need the output tables for each of the 'num' options and as well as the final table for individual analysis. It is exporting 'num' tables.
2. I sort the tables prior to execution for convenience.
3. 'run' is the value of 'num', apologies for that lack of clarity.

I'm sorry, it appears my question wasn't specific/detailed enough... I'll try to clarify

I need to filter the array for the rows that contain a value of 1 in the 8th column for each number 1:num, which is easy enough

filteredarray = youraray(yourarray(:, 8) == 1);

then the char in the 1st column of that row will be compared to a pre-existing char, that is different for each value of num and I'll need the sum of those values that do not equal the pre-existing char

char = char = ['K';'J';'I';'L';'A';'B';'C';'D';'E';'F';'G';'H';'I';'J';'K';'L']
total_errors = sum(filteredarray(:,1)~=char)

but I need the total_errors for the values 1:num in a numx1 array?

I don't know if I made this any more clear.... I'm not very good at explaining things
