# Replacing sequences in matrix

Hello everybody,
I have a matirx and I want to change the order of matrix in accordance with first column.
First column is the index start from 4 to 13 and others an offset at 100 intervals from 4 to 13.
Now it is from 4...13,104..113.. to 913. I would like to make it from 904...913,804..814.. to 13.
Is there a way to make the matrix in such an order.

Thank you very much. I really appreciate with it. The result variable is the 100 by 2 matrix. It is possible to make the order including with the 2nd column together?

"It is possible to make the order including with the 2nd column together?"
Perhaps this does what you want:
A = [4,5,6,7,8,9,10,11,12,13,104,105,106,107,108,109,110,111,112,113,204,205,206,207,208,209,210,211,212,213,304,305,306,307,308,309,310,311,312,313,404,405,406,407,408,409,410,411,412,413,504,505,506,507,508,509,510,511,512,513,604,605,606,607,608,609,610,611,612,613,704,705,706,707,708,709,710,711,712,713,804,805,806,807,808,809,810,811,812,813,904,905,906,907,908,909,910,911,912,913;16,79,31,53,17,60,26,65,69,75,45,8,23,91,15,83,54,100,8,44,11,96,0,77,82,87,8,40,26,80,43,91,18,26,15,14,87,58,55,14,85,62,35,51,40,8,24,12,18,24,42,5,90,94,49,49,34,90,37,11,78,39,24,40,10,13,94,96,58,6,23,35,82,2,4,17,65,73,65,45,55,30,74,19,69,18,37,63,78,8,93,78,49,44,45,31,51,51,82,79].'

Certainly! To reorder the matrix as you specified, you can use the following code:
clear; close all; clc;
