I am getting this error on running the following:
start(v);%v is a gige/gentl object
[recording1, time, metadata] = getdata(v, numFrames);%4D image
Error using imaqdevice/getdata (line 164)
Operands to the logical AND (&&) and OR (||) operators must be convertible to logical scalar values. Use the ANY or ALL functions to reduce operands to logical scalar values.
its pointing to getdata whose source code I am not allowed to change because it is a Matlab inbuilt function.
No issues when I just do
recording1 = getdata(v, numFrames);%4D image
Please help

Here is the answer:
Change to the following (i.e., replace && by & below):
if ~isChunkModeActive && ~any(startsWith(fieldnames(meta), "Chunk"))
return
end
Because I am unable to make this change in Matlab due to permission issues, I just generated a copy script in my local folder. And it worked

Ideally this script should be fixed by Matlab. It is their built-in function.
