I am using Fortran. Do I have to perform some operation to switch

MatCreateSeqAIJWithArrays routine?

MatCreateSeqAIJWithArrays expects a 1d array for the values [and rows,column indicies as well] - so this issue of row-major vs column-major does not exist.

Also does this routine replace the call to the MatCreate() routine?
I am assuming I still need to do the assembling of the matrix
afterwards?

You will get a fully created & assembled matrix after this call.
