I made a simple neural network program using a 'train' function.

And every time I repeated this program, the result was changed.

but if I quit a matlab and run this again, same result come out.

why this situation happening? please answer easily. thanks.

在 MATLAB Online 中打开

When you restart Matlab, the random number generator is reset which is likely the reason that you can repeat the result after Matlab is restarted. To test if this is the reason, you can manually set the random number generator using the rng command. Try for example to run

rng(1)

before each training and check if you obtain the same result.
