Sorting of arrays

[sarahwdr]

Hi
I need to write a code that will sort the absolute value of both an array that represents a vector, and an array that represents an nxn matrix. For the sorting of the vector-array I have written a program that works fine, but for the matrix I don't really know where to begin. It needs to be sorted in a way that if the 1. and 2. column of the vector-array switch place, the 1. and 2. column of the matrix-array should switch place as well. The following code I have written looks like this:

void SortNorm(double LamValsUs[NMAX], double WMatUs[NMAX][NMAX], double LamValsSo[NMAX], double VMatSo[NMAX][NMAX], int n, int r){
double temp;
int i,j;
for(i=1;i<n;i++){
for(j=0;j<(n+i);j++)
if(fabs(LamValsUs[j])<fabs(LamValsUs[j+1])){
temp=LamValsUs[j];
LamValsUs[j]=LamValsUs[j+1];
LamValsUs[j+1]=temp;
}
}
cout<<"The array is now sorted using Bubble-sort: ";
for(i=0;i<n;i++)
cout<<" "<<LamValsUs[i];
}
