1) i want to perform seperate operations all at once for different elements of a matrix. for example consider the matrix A below. i want to, lets say, add 2 to element 8 and multiply 3 with element 11. and get the final result as B. how to do it in a single line.
2) and also how to do such things with separate rows and columns.
thanks
A= [1 2 3 4 5; 6 7 8 9 10; 11 12 13 14 15; 16 17 18 19 20]
B= A= [1 2 3 4 5; 6 7 10 9 10; 33 12 13 14 15; 16 17 18 19 20]

You would need the Parallel Computing Toolbox... and a flexible definition of "at the same time".
It is unlikely to be worth the effort to set up.
