MATRIX DOES NOT CONFORM TO OPERATION, Please correct this code for me

PLease help correct this, I wish to do it by replicates.

This is the code. The data set and error message is below.

CODE

proc iml;

     use Complete_1;

    read all var _all_ into DM;   

      close;

    frequency =DM[,7]; y =DM[,6]; obs=DM[,10]; Censored= DM[,4]; time = DM[,3];  x =DM[,2];replicate=DM[,1];

      use GIB_&p;

    read all var _all_ into Col;

timeS=time;

locC=loc(censored=1); matrix=J(1,7,2.10);

do im = 1 to 1;

u = unique(Replicate);

byIdx = loc(replicate=u[im]); /* the UNIQUE-LOC trick */

byGroup = DM[byIdx,];

frequency =byGroup[,7]; y =byGroupDM[,6]; obs=byGroup[,5]; Censored= byGroup[,4]; time = byGroup[,3];  x =byGroup[,2];replicate=byGroup[,1];

do j= 1 to frequency[1];

seed=-1;

   A=RANUNI(-1);

     i=max(loc(Col[,j]-A>0));

if i<nrow(time) then   /** do nothing if the last is censored, that is         censored=1*****/

      do;

timeS[locC] = time+ (time[i+1]-time)*((Col[i,j]-A)/(Col[i,j]+col[i+1,j]));

      end;

end;

sim=repeat(im,nrow(time),1);

temp=obs||censored||time||Y||timeS||X||Sim||replicate;

Matrix=matrix//temp;

end; matrix=matrix[2:nrow(matrix),];

create impute_t_&p var{obs censored time Y timeS X  replicate};

      append from matrix;

quit;

ods trace on/listing;

proc sort data=impute_t_&p;

by replicate;

run;





variables:

col1=DM[,8]

frequency =DM[,7]; y =DM[,6]; obs=DM[,10]; Censored= DM[,4]; time = DM[,3];  x =DM[,2];replicate=DM[,1]

Re: MATRIX DOES NOT CONFORM TO OPERATION, Please correct this code for me

The error message

timeS     20 rows      1 col     (numeric)

tells you that the timeS vector is longer than the others, so you can't concatenate them together.
