basically as the title says. not sure whether this is intended.
the problem can be reproduced using the code below.
"net_2btest.mat" can be obtained here
https://github.com/TFEI-Terminal/minibatchpredict-demo/blob/83e961be22ac7c9f1109a0e22c71ed20d79c0812/net_2btest.mat
===============
load('net_2btest.mat','net');
a = rand(101,1,100);
for i = 1 : 10000000
if ~rem(i,100)
i
memory
end
b = dlarray(a,"TCB");
c = minibatchpredict(net,b);
end
===============
if you keep attention on memory. i.e., Memory used by MATLAB: xxxx MB
you`d find every minibatchpredict call uses ~500kb-1mb more memory.

Hi @Felix,
I have noticed a similar behaviour with the ‘minibatchpredict’ function when working with MATLAB R2024b. Upgrading the MATLAB version to R2025a Prerelease has solved the issue.
Hope this helps!
