Make a logical array into a single logical column, if any of the array rows contain a 1

Hi Guys i have a logical array of the size 10617x21 named a. I need it to be 10617x1 named b, so only one column.

One condition, if there was a 1 anywhere in the row on a, then i would like the row value of b to also be 1.

Smaller example:

a = [0 0 0; 1 0 0; 0 1 0; 0 0 0]

a = 4×3

0 0 0 1 0 0 0 1 0 0 0 0

b = any(a==1, 2)

b = 4×1 logical array
   0
