Modulo with expression not the same as modulo with value
Because mod(1,z) is a discontinuous function of z at 0.1, fplot(@(z) mod(1,z),[0,0.2])

For the trainNetwork function, progress plots for training are not closing, except if done manually. How do I close it? I have tried close all, close force, close(fig), & more
Try resetting your GPU. gpu = gpuDevice; reset(gpu); close all force
