Problem with select Levenberg-Marquardt train algorithm in nftool in Matlab R2020a

Hi everyone,

I have a weird issue when I try to use nftool for creating a neural network In my Matlab R2020a version. I choose Levenberg-Marquardt in the train algorithm section of nftool, but when I click the train button, in the Neural Network Training (nntraintool) window and for Training information, it shows me Scaled Conjugate Gradient!!!!

When I select either Scaled Conjugate Gradient or Bayesian Regularization, it shows correctly in the Neural Network Training (nntraintool) window.

Does anyone know why this happens?!! Any suggestions?!

I figure out that the problem is about my number of columns. My matrix is 128x31055, and because of 31055 columns, I can't use the Levenberg-Marquardt algorithm, which is why train algorithm changes after click train button.
