Dear All, Although I know how to sort a single column or row in an ascending or descending way, but I do not know how to sort a higher dimension matrix based on a single column. I hope the following example illustrate my point:
12 0 1 65
5 1 0 340
13 2 1 100
9 0 0 0
I need the matrix to be sorted based on the first column. Basically I need all rows to be sorted based on a simple sort on the first column. Here is the desired output:
5 1 0 340
9 0 0 0
12 0 1 65
13 2 1 100
I hope you will help me to figure how to sort it out! Thank you so much HRJ
