% 1. Create the net
net = newgrnn(sample_train_input,sample_train_output,0.01);
toc;
% 2. Simulate the validation set
output_valid = sim(net,sample_valid_input);
For the need, I build a grnn network.
sample_train_input is an array of 8*151066
sample_train_output is an array of 1*151066
sample_valid_input is an array of 8*18883
When executing “output_valid = sim(net,sample_valid_input)”, it prompts "The requested 151066x18883 (21.3GB) array exceeds the preset maximum array size. Creating arrays larger than this limit may take longer and will cause MATLAB to be unresponsive."
I have looked at the settings in the preset-matlab array size limit, I have set it to 100%, but I still have this problem, how can I fix it?

Hi,
This issue arises due to RAM Limitations.
  • As you have already set the Maximum array size to 100% try running the following command in the command window to check if the available memory is greater than the required 21GB.
