How to create a matrix with Na and certain values as 0

Postby lotusfr » Wed Jul 13, 2022 8:28 am

For example, I have a M=8*8 matrix and I want the default to be NA. But M(1-4,5-8) as 0

Thanks very much

Lots of different ways. Here's one:

Code: Select all

matrix(8,8) x x=na matplace(x,0*@ones(4,4),1,5)
