GPSDev Function Unrecognized- ESP32 and GT-U7

When I run the first two code segments I get NaN/NaT or just no output but no error and when I the last two I get the error "Unrecognized function or variable 'gpsdev'. I have tested the set up using the arduinoIDE and I get proper GPS output through that. I have also checked the baud rate, the communication between the esp32 and computer and that there is proper physical connection. Do you know why I am getting this error/no output? What is the best method to trouble shoot these errors? Any tips would be greatly appreciated. Thank you.

Update: Using code 3 I reinstalled the Navigation toolbox and am now getting this error:

"Error using IMUReadings

Obtaining the required NMEA sentences (RMC, GGA and GSA) is taking longer than expected. Verify the physical connection of the GPS

device to the specified serial port and the configuration of the GPS device."

1.

a = arduino('COM3','ESP32-WROOM-DevKitC','Libraries','Serial')
gps = gpsdev(a)
gpsData = gps.read;
latitude = gpsData.LLA(1);
longitude = gpsData.LLA(2);
gpsTime = gpsData.GPSReceiverTime;
% GPS returns UTC datetime. Convert it into system time zone.
gpsTime.TimeZone = 'local';
if(~isnan(latitude) && ~isnan(longitude))
    % plot the position in geographic coordinates
    fig = geoplot(latitude,longitude,'Marker',"o",'MarkerSize',6,'Color','red','MarkerFaceColor','red');
    % Sets the latitude and longitude limits of the base Map   
    geolimits([latitude-0.05,latitude+0.05],[longitude-0.05,longitude+0.05]) ;
    % Selects the basemap   
    geobasemap streets;
    timeString = strcat("Timestamp: ",string(gpsTime));

2.

    a = arduino('COM3','ESP32-WROOM-DevKitC','Libraries','Serial')
    gps = gpsdev(a)
    [tt,overruns] = read(gps)

3.

    gps = gpsdev('COM3','OutputFormat',"timetable")
    [tt,overruns] = read(gps)
    release(gps)
    gps.SamplesPerRead = 2;
    read(gps)

4.

    s = serialport('COM3', 9600)
    gps = gpsdev(s,'OutputFormat',"matrix")
    [lla,speed,course,dops,gpsReceiverTime,timestamp,overruns] = read(gps)
    
    %delete(gps);
    %clear gps;
    %clear a;

gpsdev() passed a port name or serialport() object requires the Navigation Toolbox R2020b or later.

gpsdev() passed an arduino object requires the MATLAB Support Package for Arduino, R2020b or later.

[Dara]

The Navigation Toolbox and MATLAB Support Package for Arduino are installed and I am running MATALB R2023a. This is the error I am recieving when using the last two code segments. Do you have any other ideas as to why I am recieving this error or no data? Thank you.
