A small error founded in your code.

[Spring-wind]

Thank you very much for sharing you code!
I have found a small error in line 38 of 'NLSTF.m' and line 38 of 'NLSTM_SMBF.m', where 'n=ceil(gg(i)/num2);' should change to 'n=ceil(gg(i)/num1);'
When your dataset's width and height are not equal, the original code can't work. I found that's because the column 'm' is calculated incorrectly. By changing 'num2' to 'num1', it works!
