Hello there,

I have quite big matrix with let say 1000 rows and 1100 columns.
Each of element of this matrix is a point on a surface e.g. {1.232,12.123}
How can I quickly get first element of each point for whole matrix and put
it in a vector (1000*1100 - this will be a length of that vector) without do
it in a nested loop (Do[Do[...]])?
And the similar to get the second element of each point into vector.

kind regards,
Szymon Roziewski
