How to read data one by one

The file is like
2
0.5 0.6 0.7
0.0 -2.5 6.3
The first line is the number of points. The others are the coordinates of those points x y z.
In C++, we have
ifstream fin("coordinate.txt");
fin>>num;
for(int i=0; i<num; i++)
{
fin>>array[i][0]>>array[i][1]>>array[i][2];
}
What are the corresponding code in MATLAB?

It should be sufficient to write
filename='coordinates.txt';
[x,y,z] = dataread('file', filename, '%f%f%f', 'delimiter',...
' ', 'headerlines', 1);

Thank you! But I do not think it will work for my question.
I did try it and it works on your example. Why do you think it will not work? Please note, the coordinates will be in the vectors x, y and z. If you want to store it in a matrix "array", you could simply write
array = [x,y,z];
Thanks Matz. But you know the above file is just an demonstration. So my question is: is there a command in MATLAB that will read the data one by one and it will automatically goes to a new line when comes to the end of one line?
