Filtering a matrix via User Input

Hi guys,

I am trying to create a program that will get the user to select a file and then using the inputdlg command, select a specific set of a filters, then the program will plot the file (in this case 3 columns each with x amount of rows) but filter out the data the user has specified (eg. filtering the min and max limit of column 1 will delete the row corresponding and so on for each column).

[file,path] = uigetfile('*.txt');
if isequal(file,0)
    disp('User has selected Cancel.');
else
    disp(['User has selected ', fullfile(file)]);
end
Data = readmatrix(file);

Filtering_q = {'Enter Easting Filtering Minimum (m)',...
    'Enter Easting Filtering Maximum (m)',...
    'Enter Northing Filtering Minimum (m)',...
    'Enter Northing Filtering Maximum (m)'};

Filterlims = inputdlg(Filtering_q);

Eastingmin = str2num(Filterlims{1});
Eastingmax = str2num(Filterlims{2});
Northingmin = str2num(Filterlims{3});
Northingmax = str2num(Filterlims{4});

rows_to_delete_Eastingmin = find(Data(:,1)<Eastingmin);
rows_to_delete_Eastingmax = find(Data(:,1)>Eastingmax);
rows_to_delete_Northingmin = find(Data(:,2)<Northingmin);
rows_to_delete_Northingmax = find(Data(:,2)>Northingmax);

Data((rows_to_delete_Eastingmin):(rows_to_delete_Eastingmax):(rows_to_delete_Northingmin):(rows_to_delete_Northingmax),:) = [];

E = Data(:,1);
N = Data(:,2);
D = Data(:,3);

plot3(E, N, D, '.')

This is what I have so far and everything besides the filtering works.

I am using MATLAB 2019a.

You can use OR '|' or AND '&' to combine your logical statements. you don't need to use find as matlab works directly with logical indexes.

rows_to_delete_Eastingmin = Data(:,1)<Eastingmin;
rows_to_delete_Eastingmax = Data(:,1)>Eastingmax;
rows_to_delete_Northingmin = Data(:,2)<Northingmin;
rows_to_delete_Northingmax = Data(:,2)>Northingmax;
r_del = rows_to_delete_Eastingmin | rows_to_delete_Eastingmax | rows_to_delete_Northingmin | rows_to_delete_Northingmax;
Data(r_del,:) = [];

Thank you but after running both OR | and the AND & command it hasn't actually filtered the numbers out of the Data matrix. Any more suggestions?
