How do i evaluate a matrix in row by row case?

The data set contains values that fall within the two if statemet ranges. What i would like to do is that, execute each value separatetly. so for example if a value in row 3 column 1 falls within the first if statemet range then that gets executed and if the value in row 4 column 1 falls in the second if statemnt range that also gets executed. essentially i want to look at the data in a row by row case and keep the values in separate tables for each columns.

If there is another way of doing this please share.

Testdata;

n = 0;

Dist_type = {'Kernel', 'Gamma', 'Normal','Weibull'};

for j = 1 : numel(Dist_type)

if Testdata(Testdata(:,j) > 11.23 & Testdata(:,j) < 11.19) & (n == ~ 1)

%.....

n = 1;

t1 = table(Testdata(Testdata(:,j) > 11.23 & Testdata(:,j) < 11.19))

elseif Testdata(Testdata(:,j) > 11.28 & Testdata(:,j) < 11.33) & (n == ~ -1)

% .......

n = -1;

t2 = table(Testdata(Testdata(:,j) > 11.28 & Testdata(:,j) < 11.33))

else

n = 0;

end

end

Maybe something like this is what you want:

Dist_type = {'Kernel', 'Gamma', 'Normal','Weibull'};
for j = 1 : numel(Dist_type)
    % Make two tables of the values in the jth column of Testdata that are
    % within the two ranges:
    % (Note that the first range as initially written would always contain
    % no data, so I switched it around.)
    t1 = table(Testdata(Testdata(:,j) > 11.19 & Testdata(:,j) < 11.23,j));
    t2 = table(Testdata(Testdata(:,j) > 11.28 & Testdata(:,j) < 11.33,j));
    % Do something with the tables
end

If you really want to go row-by-row, you can do that by adding a second nested for loop, but the code was already essentially operating on all rows at once.

I will try this and yes i really need to go row by row beause this is supposed to operate on a streaming data so i wont have a table or a set of data. The only other option i have is to make this work based on the last value that falls within any of those two statement....also thanks much
