About how to use cusparseScsrilu02.analysis when nnz value changed but its position unchanged

I have a confusion. When solving a system of linear equations using cusparseScsrilu02.analysis, if the non-zero values of coefficient matrix change but their positions remain unchanged, do I need to call the cusparseScsrilu02.analysis routine again?

cusparseScsrilu02_analysis() does not read from the values. You should not need to call it again if all that changes are the values.
