inverse matrix and NA value

[superjocker]

Hi, I am trying to take the inverse of a matrix with one value which is an NA. I want the inverse of this matrix to be an NA as well but it gives me an error. Anyone knows how to do this?

NA found in matrix in ""

Thanks

There isn't an easy way to do this. But something like:

Code: Select all

Matrix b = matrix a b = na setmaxerrs 2 b = @inverse(a)

Where a is the matrix you're inverting.

Hi Gareth, yes it worked but the thing is I am running a loop when sometimes the inverse of the matrix is a number (because the matrix to inverse is a number matrix) and sometimes the inverse of the matrix gives me an error (because the matrix to inverse is a na matrix). I was trying to use your code with a @recode, but dindt work.

Should still work. Just increase allowed errors

Yes, it is working, thanks Gareth.
