sym/besseli - Too many input arguments.

I amd trying to make a symbolic function using "Modified Bessel function of first kind" (besseli) through which the x is the symbolic variable. Although the followig expression:

>> syms x

>> mySymFunc=besseli(0,x);

works well, however, this expression:

>> syms x

>> mySymFunc=besseli(0,x,1);

using the scale value as the third input (here for example 1) will lead to the following error:

"Error using sym/besseli

Too many input arguments."

I would like to ask you if there is any possible solution to overcome this issue.

Regards,

There is no third argument in the symbolic function "besseli":
