@Matevz Lavtar: From the error log that you have posted, the usage of the command is incorrect. To use a irSensor, kindly use the following syntax

>> myev3 = legoev3('USB');
>> mySensor = irSensor(myev3, <inport>);

where <inport> is the input port to which you have connected the IR sensor. (1 to 4)

I cannot read data from infrared sensor. Could someone help me please with this error:

>> myev3 = legoev3('USB');
>> myirsensor = irSensor(myev3)
Error using fusion.internal.remotesensors.ScanningMount (line 381)
Invalid property/value pair arguments.

It does not work. Downloading of the "third party packages" does not work.
What is the problem with that?

I don't know what people are complaining about - this worked very easily for me in Matlab 2018A, Win10. Great!

@Suhail:Which open source code are you referring to?

how to access the open source code after installing the support package

Hey guys.
Disable your antivirus if you're having trouble installing third party packages.

I cannot install this support package. I had it installed on my previous computer running MatLab 2016 with no issues, but now I can't install it with 2017.

I doesn't work. The brick is connected with the computer. The low level matlab instruction works, but not this package.
deviceInfo = instrhwinfo('Bluetooth','EV3CB')

deviceInfo =

HardwareInfo with properties:

RemoteName: 'EV3CB'
RemoteID: 'btspp://0016534C257F'
ObjectConstructorName: {'Bluetooth('EV3CB', 1);'}
Channels: {'1'}

It doesn't work. Can't install the support package :(
