Hi,
Please kindly help me with a short program that can do this computation using T.length and X.length. Please find my computation in matlab below and the instruction on every step.
Thanks in advance
Jonathan
The final computation answer is also given
T= [5.1000 3.5000 1.4000 0.2000;
6.4000 3.2000 4.5000 1.5000;
5.4000 3.4000 1.7000 0.2000;
5.7000 2.8000 4.5000 1.3000;
5.7000 4.4000 1.5000 0.4000;
5.6000 2.9000 3.6000 1.3000];
X = [
5.1000 3.8000 1.9000 0.4000;
6.4000 2.9000 4.3000 1.3000;
4.3000 3.0000 1.1000 0.1000;
5.4000 3.0000 4.5000 1.5000];
Z1 = T - X (1, :);
Z2 = T - X(2,:);
Z3 = T - X(3,:);
Z4 = T - X (4,:);
% get the square of each rows%
Z1 = (Z1.^ 2);
Z2 = (Z2.^2);
Z3 = (Z3.^2);
Z = (Z4.^2);
% get the sum of each matrices %
Z1 = sum(Z1, 2);
Z2 = sum(Z2, 2);
Z3 = sum(Z3, 2);
Z4 = sum(Z4, 2);
% get the square root of the numbers in each matrices to get the
% distance%
Z1 = sqrt(Z1);
Z2 = sqrt(Z2);
Z3 = sqrt(Z3);
Z4 = sqrt(Z4);
