Vector sum of forces

I am given a 1468x3 matrix. The columns represnt Fx, Fy, and Fz (components of force in x, y, z directions)

I need to find the resultant force.

I know that the formula for this would be (Fx^2+Fy^2+Fz^2)^.5, but how do I do this in matlab, for all 1468 columns?

The result should be a 1468x1 matrix.
