Matrix Configuration in Matlab

Hi guys and gals. I have the following equation in Matlab:

TSR_local=r_over_R*TSR;

which then gives the following matrix:

TSR_local =

    0.4444
    0.8889
    1.3333
    1.7778
    2.2222
    2.6667
    3.1111
    3.5556
    4.0000

But when I apply it to the following equation the result is a 9x1 instead of a 1x9: Phi=(2/3)*atan(1/TSR_local);

Phi =

         0         0         0         0         0         0         0         0    9.3575

Does anybody know how I can get the desired 9x1 configuration from the second equation? Thanks for the help.

Best regards, Kevin

Phi=(2/3)*atan(1./TSR_local);

Notice the added dot.
