How to compare previous column values of all rows to the current column value with a user defined criteria

Hello MATLAB Experts,,

i am stuck at a problem.. please help in solving this..

the Question is:-

i have a matrix A = 2x6. Now, i want to append to it 8 more rows to make it 10x6 .. to do this, for the first 4 columns i am sampling using randi in range [20,100]. i want sampled value for each column in a way (abs(sampled_value-all_previous_row_values_of_same_column)/100-20)>15. that means i want to compare the current sampled value of a collumn with all the previous row values of same column using the criteria written in bold. we will consider the sampled value only if satisfies criteria for all previous row values .. similarly i want to do for next 3 columns. if all 4 columns satisfies the criteria, we will add the rest 2 columns(5 and 6) to the new row as it is.and add the created row to the matrix A.

please help me in doing this..

Thank You in advance

I don't know exactly how you'd do "abs(sampled_value-all_previous_row_values_of_same_column)". Can you provide an actual example with actual numbers?
