Is there a MATLAB function that calculates the magnitude of a velocity vector?

v(t) = sqrt( x(t)^2 + y(t)^2 + z(t)^2 )

Answer 1

[Walter Roberson]

if x y z are scalar then

 norm([x, y, z])

[Walter Roberson]

For non-scalar,

v = sqrt( x.^2 + y.^2 + z.^2 );

[Steven Lord]

If you have multiple vectors whose norm you want to calculate stored in a matrix and you're using release R2017b or later, use the vecnorm function.

Steven, Thanks.
