problem with using GPU in matlab

Hi i have a problem with using GPU in matlab. I bought GTX 1050 ti last week and connected to my computer. After then, i ran a code that represent a calculating time of both my cpu and gpu. (using tic & toc function) https://kr.mathworks.com/matlabcentral/fileexchange/46710-tutorials--parallel-and-gpu-computing-with-matlab--9-of-9---gpu-computing-with-matlab.

However, there was no difference between them. It showed similar speed. In this situation, what shall i do? (I want to make GPU speed faster than CPU's)

And also can anyone tell me the best way to use deep learning algorithm with my cpu (Intel Core i7-6700)?

p.s) My computer has Inter Core i7-6700 as a CPU, GTX 1050ti as a GPU,and 32GB RAM (if you guys want to know another information about my computer, please let me know i'll reply as soon as possible)

The GTX 1050 doesn't have very good double precision performance, and the default precision for all MATLAB computation is double. Try running your code in single precision. Check out GPUBench as a handy way to test the performance of your GPU.

Thanks, i should change GPU to solove this porblem. :)
