Understanding the conditional output beginning with (t == 0 | v == 0)

Upon integrating a time dependent variable, an exerpt to my solution contains the following: (t == 0 | v == 0) & m ~= n & m + n ~= 0 & 0<= v*t, the solution... I seem to understand every other thing except for this (t == 0 | v == 0). I need an explanation to (t == 0 | v == 0) please. Thank you.

logical (t==0 or v==0)

t=randi(5,1,20)-1

t = 1×20

2 3 3 1 2 4 3 3 3 0 3 4 4 4 1 3 1 2 0 4

v=randi(5,1,20)-1

v = 1×20

4 2 1 0 0 0 0 2 1 2 1 0 4 4 4 3 2 3 0 4

idx=(t==0|v==0)

idx = 1×20 logical array
   0   0   0   1   1   1   1   0   0   1   0   1   0   0   0   0   0   0   1   0
