I have a program, where I want to check if is it possible to use CUDA calculation.
gpuDeviceCount
ans =
1
says that I really do have a gpuDevice. However if I try to issue the
GPU_spectra=gpuArray(double(kiserletek.ROI_spektrumok(1).spectra));
There is a problem with the graphics driver or with this GPU device. Be
sure that you have a supported GPU and that the latest driver is
installed.
Caused by:
The graphics driver was found, but it is too old. The graphics driver
on your system supports CUDA version 6.5. The required CUDA version is
9.1 or greater.
The command
helyi_GPU=gpuDevice();
Error using gpuDevice (line 26)

also gives an error.
It is OK, I understand it. This is my home computer where I have an old video card. At work I have a newer one.
BUT! How to check if my video card is capable of CUDA calculations in order to avoid the error message?????
Matlab version is: 2018b

The reference material indicates that the GeForce 210 was rather early and supported only cuda 1.2. MATLAB never supported 1.2. The first that MATLAB supported was 1.3 because it was 1.3 that added double precision support .

Dear Walter, I accept your answer (try/catch) because it really solves my problem, although I knew it before as well. BUT I have to add that this behaviour of gpuDeviceCount is an error IMHO.
