Connect PICO 3405D MSO using MATLAB R2021b

Hi all,

I am trying to connect a properly functioning device —— PicoScope 3405D(MSO) to MATLAB R2021, running on Windows 11 Home Chinese Edition.

I have successfully downloaded PicoSDK_64_11.1.0.418, PicoScope Support Toolbox, and the PicoScope 3000 Series A API MATLAB Generic Instrument Driver for Pico 3405D MSO, and added the file paths to MATLAB.

The contents related to Pico 3405D MSO in the SDK\lib folder are as follows:

The contents of the extension folder for the 3000 Series are as follows (the address of the first image folder is 'E:\MATLAB\R2021b\PicoSupport\ps3000a', and the address of the second image folder is 'E:\MATLAB\R2021b\PicoSupport\ps3000a\win64'):

However, when trying to run the program I wrote by referring to the PS3000A_ID_Block_Example.m script (the example script provided by Pico),

I received the following error message:

Error using instrument/delete (line 82)

Operation failed: An error occurred while executing the driver disconnect code.

Dot-based indexing is not supported for variables of this type.

If this error is not an instrument error, use MIDEDIT to inspect the driver.

Error in icdevice (line 376)

delete(obj);

Error in main3 (line 15)

ps3000aDeviceObj = icdevice('picotech_ps3000a_generic.mdd', ''); % Create PicoScope 3000a device object

I found an issue: When the code is encapsulated into a function using "function", the program will report an error, but when "function" is removed, the program runs successfully. However, I still can't solve this problem.

Any help would be appreciated,

Many thanks!
