I am trying to understand direct limits in the category of $C^*$ algebras-algebras by self reading. My last question was also related to direct limitlimits. Here is my another doubtof my doubts:

letLet $(A_n,f_n)$ be a direct sequence of $C^*$ algebras-algebras. Does the direct limit behavesbehave well with matrices i.e. $$\lim_{\rightarrow} M_2(A_n)=M_2(\lim_{\rightarrow} A_n)$$ Where for the system $M_2(A_n)$ the connecting maps are the natural maps obtained using $f_n$ componentwise.

I do feel like the result should be true, but I don’t really have an argument. Any ideas?

Behaviour of direct limit with matrices
