Function Documentation

Petra_RDP_CRS_Matrix * readMatrixIn	(	FILE *	dataFile,
		Petra_Comm &	Comm
	)

Read in the matrix B (16x24 in little example) Assuming following file format: line 1 Number of rows in F line 2: max of elements in vector NumNz line 3:numnz+2 d (number of nonzeros per row) next line is total number of nonzeros rest is d d g (i,j,s) matlab sparse format

read in i,j,s values for B matrix – vh next line is number of nonzeros rest is d d g

number of nonzeros in matrix and length of i,j,s

now fill in the matrix values row by row

i.e., for each row...

set number of entries, values, column indices

Petra_RDP_CRS_Matrix * readRectMatrixIn	(	FILE *	dataFile,
		Petra_Comm &	Comm
	)

Read in the rectangular matrix Assuming following file format: line 1 Number of rows line 2: max of elements in vector NumNz line 3:numnz+2 d (number of nonzeros per row) next line is total number of nonzeros rest is d d g (i,j,s) matlab sparse format

read in i,j,s values for B matrix – vh next line is number of nonzeros rest is d d g

number of nonzeros in matrix and length of i,j,s

now fill in the matrix values row by row

i.e., for each row...

set number of entries, values, column indices

Petra_RDP_Vector * readVectorIn	(	FILE *	dataFile,
		Petra_Comm &	Comm
	)

Read in a vector. Assuming following file format: line 1 Length of (dense) vector line 2 is number of nonzero elements in vector rest is d g (i, s) indices/values of non-zeros
