how to store coordinate values xy[] for randomly generate point

for i=1:NumOfNodes

S(i).xd=rand(1)*xm;

S(i).yd=rand(1)*ym;

end

from this given code I can store coordinate of randomly generate point in matrix format but

How could I store coordinate of randomly generate point xy=[3.7739 88.5168; ........]; like this format .

Try one-liner, no loop.

xy=[xm*rand(NumOfNodes,1), ym*rand(NumOfNodes,1)]

thank you very much

The format you used (based on the code you provided) is a structure and the format you are looking for is an array. To generate an N by 2 array as you specified you can do the following:

N = 20;
xm = % some value
ym = % some value

xy = rand(N,2).*[xm ym];

suppose xy = 100*rand(n,2);

after few operation the value of x y cordinate value will be changed .

how could I implement into my MATLAB code?

thanks in advance
