Strange behavior of C compiled program
Hi the list,
I need to include some C code in R, but the behavior of the C code is
strange : Here is my code :
--- 8< ---
Rprintf("\n XXXX mTraj=%f
mClus=%f",mTraj[i+nbId*c],mClustersCenter[j+nbClusters*c]);
Rprintf("\nDistA=%d Tmp=%d",dist,tmp);
tmp = mTraj[i+nbId* c] - mClustersCenter [j+nbClusters* c];
Rprintf("\nDistB=%d Tmp=%d",dist,tmp);
dist += (tmp * tmp);

matrix to a C function
Hi the list,
Is there a way to give a matrix to a C function, and then to use it as a
matrix ?
I write a function to print a matrix, but I use it as a vector :
1. void printMatrix(double *mTraj,int *nbCol, int *nbLigne){
2. int i=0,j=0;
3. for(i=0 ; i < *nbLigne ; i++){
4. for(j=0 ; j < *nbCol ; j++){
5. Rprintf(" %f",mTraj[i * *nbCol + j]);
6. }
7. Rprintf("\n");
8. }
9. }
I would like to use it as a matrix (line 5 changes) :
