For loop to enter data into a Cell array by calling functions. Creating an array with 'n' number of rows. Displaying content onto a uitable

Hello Everyone,

I'm trying to make a simple student database. I'm trying to display the data onto a uitable. Now my problem is how do I make this program run 'n' number of times and store the data into a new row every time data is added. eg when 2 students are selected to be in a specific course, there would be 2 rows in the uitable with the 2 students' names. Here's the main script file:

*disp('Welcome To The Student Directory')

e = menu(' ');

p = numbers; %function to ask how many students

for x=1:p

if e == 1

Cell = {name,ID,total}; %functions for the name, ID, and total marks (which contains CW and final marks functions etc) end

if e == 2

Cell = {ID,name,total};

end

end

a = uitable;

fprintf('Thank you for using our program \n A window will open displaying the Students Name alongwith their total marks and Grade \n')

ColName = {'Name','ID','Total Marks','Grades'};

uitable('ColumnName',ColName,'Data',Cell);*

oh and I thought of making a vector for EACH of the functions (eg name, ID, total, etc) but then if the number of students selected is 5, the function will ask for ALL 5 names before moving onto ID and so on.

How do i make it loop ALL the functions 'n' number of times (i.e. 'n' students) and store it onto a cell array with one row displaying all the data for ONE student? I'm new to MATLAB :( any help would be greatly appreciated :)

Thanks so much for your time !

Sorry dint notice the code was so badly formatted =/ Anyway, I've read up on structs. I was wondering which is better to display the results?

Hi Harith,

You probably want something like this:

for row=1:nStudents
    Cell{row, 1} = Name;
    Cell{row, 2} = ID;
    Cell{row, 3} = Total;
    % Do this for all values in a given row.
end

Bear in mind that a uitable cannot display data that is in a structure array. It can only display numeric, logical, or cell data. And if you are using a cell array for your data, that cell array must contain only numeric, logical, or string values.

I hope this helps!
