X_ISMD = 995152.969208341;
Y_ISMD = 996113.117131325;
for i = 1:length(data1)
D1(i) = sqrt((X_ISMD - X_WGS84(i)).^2 + (Y_ISMD - Y_WGS84(i)).^2);
end
D1
length(data1) is 172. X_WGS84(i) and Y_WGS84(i) are 172 by 1 matrix. according to the above matlab code i ma getting following output (1 by 172 matrix). but i want to have 172 by 1 matrix. could you please suggest where should i change in my code? Thanks.
D1 =
Column 1
140911.995295475
Column 2
123232.133401588
Column 3
115208.35805542
Column 4

X_WGS84 =randn(172,1);

D1 = D1.' % Transpose
