Removing a row from a matrix based on certain conditions

I have three variables t_SS, t_A, and G and all of them have the size of 10000 X 8. I'm looking for away to remove the entire row in G if any of the following coniditions is met. Below is my code and does not work properly since if G is deleted in the first conidtion, the number of index change.

Not sure how to fix it and thanks in advance.

Index_N_tS   = find(t_SS < 0);
Index_N_tA   = find(t_A < 0);
Index_less_A = find(t_A < t_SS); 

I have to check these cells are not empty:

indx1_tS = isempty(Index_N_tS); 
indx1_tS = isempty(Index_N_tS); 
indx3_tA = isempty(Index_less_A)

% if any of the condition is met, remove the entire row in G

if indx1_tS == 0  
    G(Index_N_tS ,:) = [];  
end 
if indx2_tA == 0
    G(Index_N_tA,:) = [];  
end
if indx3_tA == 0 
    G(Index_less_A,:) = [];  
end 

Thank you

You do not explain how you want to handle the 8 columns in your logical comparisons: do you only want to remove the entire row if any column meets that condition, or if all columns meet that condition?

Here is a solution that works for any column meeting those conditions:

idx = any(t_SS < 0 | t_A < 0 | t_A < t_SS, 2);
G(idx,:) = []

You will need to decide if any or all or some other column handling is what you need.

so if any of the condition met, I will remove the entire row which means all the columns.
