Hello Nicole

From the error that you have mentioned, I understand that whatever you are passing as argument is not a double or is not a scalar.

As you are using double conversion function "double(...)", so the problem must be that the number is not scalar. There is a possibility that the argument you are passing can be a complex number or a vector. So, try to trace the value of "Liqdensity" you are passing, by debugging and make sure you are passing correct type of argument. I suggest you use "num2str" to convert complex numbers into strings. You can use "dbstop if error" and check the value stored in "Liqdensity".

Hope it Helps
