Naming variables according to the values of another variable

I have a variable
A=[1;2;5]
and I want to use the values of this variable in the name of the new variables I'm going to create: B_1, B_2 and B_5.
for k=A(1,1):A(3:1)
B_'k'= TreeBagger(.)
end
This code, however, doesn't work and I couldn't come up with a solution.

Formcing meta-data into variable names is one way that beginners force themselves into writing slow, inefficient, complex code that is difficult to debug. Read this to know some of the reasons why:
You should store (meta-)data in variables (not in variable names) and use basic indexing, just like MATLAB was designed for.

Don't do this. Hiding indices in the names of variables is a bad programming pattern, which is avoided consequently by experienced programmers. See https://www.mathworks.com/matlabcentral/answers/304528-tutorial-why-variables-should-not-be-named-dynamically-eval
Use array and indices or a struct instead.
for k = 1:3
B(k).index = A(k);
B(k).data = TreeBagger(.)
end
By the way, A(1,1):A(3:1) might not do, what you expect. The 2nd argument is an empty vector. Maybe you mean:
for k = A.'
