Modify an element or a row of a matrix : subsop

subsop modifies an element or a row of a matrix. It is used mainly for Maple and MuPAD compatibility. Unlike := or =<, it does not require to store the matrix in a variable.
subsop takes two or three arguments, these arguments are permuted in Maple mode.
  1. Modify an element

  2. Modify a row
Remark
Note also that subsop with a 'n=NULL' argument deletes row number n. In Xcas mode input :
subsop([[4,5],[2,6]],'1=NULL')
Output :
[[4,5]]
