Newindex

We can change the value of single elements or rows of a matrix by assigning new values to the indexed elements

Example.Quanty

A = Matrix.New({{1,2},{3,4},{5,6}})
print(A)
A[2][2] = 0
print(A)
A[3] ={7,8}
print(A)

{ {  1      ,  2      } ,
  {  3      ,  4      } ,
  {  5      ,  6      } }
 
{ {  1      ,  2      } ,
  {  3      ,  0      } ,
  {  5      ,  6      } }
 
{ {  1      ,  2      } ,
  {  3      ,  0      } ,
  {  7      ,  8      } }
