What's the special notation? I'm studying "ALGORITHMIC AND HIGH-FREQUENCY TRADING". Page 249 of it tries to find a formula for $h(t,q)$. First, it supposes $h(t,q) = \bar\kappa log  \space\omega(q,t)$ then let $\omega(t)=[\omega(t,\bar{q}),\omega(t,\bar{q}-1),...,\omega(t,q)]'$. 

My question is: "What is the meaning of notation $'$, in $\omega(t)=[\omega(t,\bar{q}),\omega(t,\bar{q}-1),...,\omega(t,q)]'$? 
Is it Lagrange's notation for differentiation? 

Following, I added a photo of this page. I marked the notation which I mean.
It is the transpose, in this case of the vector.
