I have a matrix that contains ( 6 rows, 2 columns) as shown in the attached image.

I'd like to have a new matrix (in MATLAB) that contains the second columns arranged in ascending order, but would like to keep their corresponding values in the in the row. for example: the output matrix looks like this

在 MATLAB Online 中打开

Use the sortrows function:

A = [1 1; 3 8; 5 9; 6 3; 7 24; 8 8];
B = sortrows(A, 2)
B =
     1     1
     6     3
     3     8
     8     8
     5     9
     7    24

Neural networks are not currently an area of my expertise. I studied them extensively many years ago, and used the first few releases of the Neural Network Toolbox, but I have not used them recently.

First see the documentation for Getting Started with Neural Network Toolbox. Then see the documentation for Classify Patterns with a Neural Network. Those should get you started.
