Undefined function 'eq' for input arguments of type 'table'.

I have taken a random sample of 6000 out of a data set of 30000. I now want to remove this sample from my original dataset to conduct analysis on the now "new" 80% of the original. I am using the below code but getting the error above.

%%Randomly Select 6,000 observations (20%) without replacement 

Test_data = datasample(Data,6000,'Replace',false);

TestData = array2table(Test_data);

Test_CustID = TestData(:,1);

sort1 = sortrows(Test_CustID,1);

   for i = 1:6000;

       Condition = sort1(i,1);

       Sample = Data(:,1)==Condition;

       Data(Sample,:)=[];

   end

Data(:,1) is an Nx1 table, and tables don't have math r relational operators defined on them. You need to compare the first variable in Data to condition. You could use Data{:,1}, but Data.Var1 would be much more readable. Actually, I have no idea what the first variable in your table is really called, substitute its real name for "Var1".
