- Initialize the CRS structure:
- Create three empty arrays:“val”,“rind”, and“cind”.
- “val”will store the non-zero values of the matrix.
- “rind”will store the row indices corresponding to the non-zero values.
- “cind”will store the column indices corresponding to the non-zero values.
- Traverse the matrix:
- Iterate over each row of the matrix.
- Within each row, iterate over each column.
- If the element at the current position is non-zero, store its value in the“val”array.
- Store the row index in the“rind”array.
- Store the column index in the“cind”array.
- Finalize the CRS structure:
- After traversing the entire matrix, store the total number of non-zero elements in a variable,“nnz”.
- Append a zero at the end of the“val”array.
- Append the value“nnz”at the end of the“rind”array.
- Append the value“nnz”at the end of the“cind”array.
