Unrecognized function or variable 'visadevlist'.

Hi everyone,

The ability to use VISA in MATLAB using the visadevlist and visadev functions were added in R2021a. However, when I go to use these functions, they are unrecognized. Do these functions require any toolboxes? The documentation does not seem to list any.

This is the version I am running these on:

MATLAB Version 9.10 (R2021a)

These functions are part of the Instrument Control Toolbox. You need to have that toolbox installed in order to use these functions. You can check if it is installed using the ver command.

If it is not installed but your iicense includes it, you can use the Add-ons explorer to add it.

When searching the documentation, the left navigation pane can be used to determine what toolbox a function is in.

I have installed ICT but visadevlist and visadev return the error Unrecognised function or variable 'visadevlist'.

Any solutions for this? Thank you.

What version of MATLAB are you using? These functions were introduced in R2021a. You must be using that version or newer in order to have access to them.
