inline matrix n x n input

hi guys I'm writing a program that uses the jacobian of a matrix, but whenever I input it using "inline" command it does not work. can someone help?

ex: i want to input the 2 by 2 matrix [2*x1 x2; 1.5*x3 x4]

but if i use f = inline('[2*x1 x2; 1.5*x3 x4]'); it gives me an error.

and if i use f = inline('2*x1 x2; 1.5*x3 x4'); then it's not a 2 by 2 matrix

The input argument to the inline function is automatically determined by searching expr for an isolated lower case alphabetic character, other than i or j, that is not part of a word formed from several alphabetic characters.

So in essence you cannot use x1 or x2 ....

You may want to try an anonymous function instead.
