Run adalm-pluto's cod on matlab

Hello:

When I run the function ad9361_LTE.m, I will get error like that:

When  "libiio_if/findAttribute" is called, no value is assigned to the output parameter 'ch' (which may also contain other parameters)

error  libiio_if/writeAttributeString (line 682)
            [ret, ch, attr] = findAttribute(obj, attr_name);

error  iio_sys_obj_matlab/stepImpl (line 311)
                        writeAttributeString(obj.iio_dev_cfg.cfg_ch(i).ctrl_dev,
                        obj.iio_dev_cfg.cfg_ch(i).port_attr, str);

error  ad9361_LTE (line 127)
stepImpl(tx, inputTX);

I got the code from https://github.com/analogdevicesinc/MathWorks_tools/blob/master/hil_models/legacy/LTE_MATLAB/ad9361_LTE.m

Hope you can help me,thanks!
