Thanks for reporting (and for confirming Doug). This is known and previously reported as bug #42152 (and bug #45423), closing as a duplicate.

x=3
X=sym([1,x;0,1]);

syms x
X=sym([1,x;0,1]);

but
X=sym([1,x;0,x]);

Symbolic toolbox: can't define (2x2) matrix with only one symbolic variable.

Example:

>> syms x
>> X=sym([1,x;0,1]);

error: octave_base_value::map_value(): wrong type argument 'scalar'
error: octave_base_value::parent_class_name_list(): wrong type argument 'scalar'
error: evaluating argument list element number 1

>> X=sym([1,x;0,x])

X = (sym 2x2 matrix)

[1 x]
[ ]
[0 x]
