Set Platform Preferences using a variable

uday_guntupalli

All, 

     I am trying to set platform preferences dynamically based on User Input collected using a UI. 

     Essentially, the user specifies which Matlab version is installed on their machine and I am using that to construct a 32-bit and a 64-bit path to the root variable for Matlab on the users machine.  However, this repeatedly results in an error: 

 

Unexpected "\MATLAB\R2018a\". Perhaps there is a missing "," or ")".
Trying to parse arguments of function "MATLABROOT32".

 

        Any help or advice is appreciated. 

 

</CODE><CODE class=" language-jsl">user_matlab_ver = '2018a' ; // for example <BR />matlab_32bit_path = "C:\Program Files (x86)\MATLAB\R2018a\";
matlab_64bit_path = "C:\Program Files\MATLAB\R2018a\";

Eval( Parse( Eval Insert("\[ Platform Preferences( PathVar( MATLABROOT32( ^matlab_32bit_path^ ), MATLABROOT( ^matlab_64bit_path^ ) ) );]\" ) ) );

ConnectToMatlab = Expr(
	matlab_conn = MATLAB Connect();
	matlab_conn_flag = matlab_conn << Is Connected;
);

ConnectToMatlab;

Thanks to @gblatz , the following works: 

 

Eval(
	Parse(
		Eval Insert(
				" Platform Preferences( PathVar( MATLABROOT32( \!"^matlab_32bit_path^ \!" ), MATLABROOT( \!"^matlab_64bit_path^\!" ) ) );"
			   )
	     )
   );
