Hi, I'm using the 2016a version and syms doesn't work as a vector.
I try:
syms a [1 4]
but I take "Not a valid variable name" error.
I know I can use sym instead:
sym('a', [1,4])
However, my request is not to use like a (1),I want Matlab to recognize it when I type a1.

The only way seems to be to actually type:
syms a1 a2 a3
I experimented with str2sym to do this, without success.
You can use sprintf or compose to create a vector of symbolic variables to manually copy and paste to your syms call :
a = compose("a%d", 1:5)
however that appears to be the only way to do what you want.

syms(sym('a', [1 4]))
