i am gettting following error.
Expected either a logical, char, int, fi, single, or double. Found an mxArray. MxArrays are returned from calls to the MATLAB interpreter and are not supported inside expressions. They may only be used on the right-hand side of assignments and as arguments to extrinsic functions.
can anyone help me to fix it?

Try to define the value first. Then, make the call which returns the MxArray.
