MATLAB: Using for loops to generate an array

arraysfor looploopsmatrix manipulation

I need to generate the array A = 1 2 3 4 5; 2 4 6 8 10; 3 6 9 12 15; 4 8 12 16 20; 5 10 15 20 25; using for loops. Don't have much experience with looping, and currently trying to understand it until it clicks. Help!

m = 7; n = 6;
A = zeros(m,n);
for i=1:m
  A(i,:) = i:i:i*n;
end

This should work for any size array with rows m and columns n.

MATLAB: How to delete data from GUI uitable with a push button

Set a pushbutton callback to edit the data in a uitable. You'll need a way to access the handles of the figure your uitable is contained in. One way to do this is to pass the handles through the callback, or you can use the 'tag' property on your figure and use findobj() in the callback. I'd use guidata() to access and save your handles if you're using findobj().

MATLAB: Allocating values in a 3D array using nested for loops

Since this is apparently a homework assignment, I will get you started. Since the requirement is to use nested loops, I assume the instructor wants a loop for each index. So here is the outline, one loop for each index:

A=zeros(3,2,4);
for z = __:__
    for y = __:__
        for x = __:__
            A(x,y,z) = ____;
        end
    end
end

I will leave it to you to fill in the blanks.
