Lakeshore 331 Temperature Controller Remote Communication with MATLAB

I am trying to communicate with a Lakeshore 331 Temperature Controller via RS-232 serial interface. I would like to query the instrument's identification information and current temperature reading. I am using the following code, but the output comes back jarbled:

lakeshore331 = visa('ni','ASRL3::INSTR');
set(lakeshore331,'InputBufferSize',3000000,'Timeout',5.0);
fopen(lakeshore331);

iden = query(lakeshore331,'*IDN?')

temp = query(lakeshore331,'KRDG?')

fclose(lakeshore331);
delete(lakeshore331);
clear('lakeshore331');

Here's the output that results:

iden =

LÓCI,ÍOÄEL³³1E,³°¶°¶1,°³2³°1
Š

temp =

«7¹®¹¹8
Š

Do you have any suggestions for how to clean up the output?
