I have a matirx datasetA (7*7), and I want to get the inverse matrix of this datasetA and save this inverse matrix in datasetB. Could you please tell me how to implement it using sas?
It is IML thing. You'd better post it at IML forum
https://communities.sas.com/t5/SAS-IML-Software-and-Matrix/bd-p/sas_iml
,and calling @Rick_SAS
data A; input a1-a7; cards; 1 2 9 5 5 6 7 4 2 3 1 5 6 4 1 4 6 2 9 6 3 6 8 7 3 8 6 2 8 7 8 8 9 6 1 3 1 3 9 1 6 6 2 7 3 4 2 6 7 ; proc iml; use A; read all var _all_ into a[c=vname]; close; inv_a=inv(a); create B from inv_a[c=vname]; append from inv_a; close; quit;
