How to add some values between two points？
显示 更早的评论
Dear everyone, Now I have some coordinates pairs and I want to add more points in the area.
For example, If I have the dataset
A = [1,2;2,2;1,3;2,3]
I want to get the matrix
B = [1, 2 ; 1.1, 2; 1, 2.1 ;1.1, 2.1; ..... ; 1.9, 2.9; 2.9, 3; 2, 2.9 ; 2, 3 ]
Thanks a lot

In here, I didn't use any special function. but the result looks not bad
Xmin = 1;
Ymin = 2;
Xmax = 2;
Ymax = 3;
step = 0.1;
step_1 = 1/0.1;
K = (Xmax-Xmin)*(Ymax-Ymin)*step_1*step_1;
Co = zeros(K,2);
n_Co = 1;
for i = Xmin:step:Xmax
for j = Ymin:step:Ymax
Co(n_Co, 1) = i;
Co(n_Co, 2) = j;
n_Co = n_Co+1;
end
end
My result is in the following

Except that's not what you originally asked for. Originally you had the first column increasing every row.

r = linspace( min(A(:,1)), max(A(:,1)), 11 );
c = linspace( min(A(:,2)), max(A(:,2)), 11 );
11 is needed instead of 10 because you need to include the final value.

How about this:
n = 20 % Whatever...
A = [1,2;2,2;1,3;2,3]
% Make new linearly interpolated array.
A2 = imresize(A, [n, 2])
A2 = A2(3 : end-2,:)
