Arduino Mega 2560 LIS3DH Undefined Function

Hey there! I am getting this weird error when trying to use the LIS3DH library.

My code:

% accelerometer

clc

clear

close all

a=arduino("/dev/cu.usbmodem1101","Mega2560");

accelerometer = lis3dh(a)

accelReadings = readAcceleration(accelerometer)

The error:

Error using accelTest (line 8)

Invalid default value for property 'IsDataReady' in class 'lis3dh':

Undefined function 'boolean' for input arguments of type 'double'.

Copilot instructed me as follows, and this solved the problem:

which lis3dh -all

This would find the lis3dh class. It then instructed me to open the file and replace all instanced of boolean() with logical(1) or logical(0) or true or false. I replaced all instances of boolean(1) and boolean(0) with true and false respectively, and then in cases where the boolean function had another parameter, I just replaced it with the logical() function as copilot instructed.

I then cleared the classes with

clear classes

as copilot instructed, and restarted matlab as copilot instructed. This would create the variables with the new lis3dh class. I then ran the code, and it worked!
