Is there anyway that I can see the value of a variable while the programs is running?
Thanks a lot!作者: shiyiming 时间: 2006-1-23 14:51 标题: to Jessie888 data yourdataset / debug;
启动DEBUG窗口后，用'e 变量名'命令显示当前值。
具体使用方法请参考SAS HELP，里面写的很清楚详细。作者: shiyiming 时间: 2006-1-24 05:08 标题: do you know how to solve the matrix equation? Thanks a lot!
I have a big problem right now. anyone can help me with that?
matrixa* matrixb*...*matrix(n-1)*inv(matrixn)=0
matrixa .... matrixn contain some variables. Now I want to solve the above equations to obtain these variable. and I cannot work out the explict form of the above equation. any funtion for this question? I know there are some if AX=C THEN x=inv(A)*C. but now I don't know A.
