## Augmented Matrix Issues...

Maple 17

How do I get values out of solved augmented matric in 2D math input? I cannot simply assign the solutions to a value by x:=A[1,5}, because it's an augmented matrix.

## Error Invalid If Statement...

Maple 17

I keep getting an error about the while. It is calling it an invalid if statement.  It may relate to semi colons, but I cannot find any errors myself. Please help.

InterpolIDW2:=proc(n,rwin,mink,p,R,IR)

local ix,iy,i,j,i0,i1,j0,j1,k;

local count,wgt,top,bot,hp;

print(`n=`,n,`rwin=`,rwin,`mink=`,mink,`p=`,p);

hp:=p/2;

for iy from 1 to n do

for ix from 1 to n do

if (IR(ix,iy)=0) then

i0:=max(1,ix-rwin);  i1:=min(n,ix+rwin);

j0:=max(1,iy-rwin);  j1:=min(n,iy+rwin);

while (k<mink )do

if(i0>1) then

i0:= i0-1;

end if;

if(i0<1) then

i0:=i0+1;

end if;

if(j0>1) then

j0:=j0-1;

end if;

if(j0<1) then

j0:= j0+1;

end if;

end do;

top:=0;  bot:=0;

for j from j0 to j1 do

for i from i0 to i1 do

if (IR(i,j)<>0) then

wgt:=1/evalf[14](((ix-i)^(2)+(iy-j)^(2))^(hp));

top:=top+wgt*R(i,j);

bot:=bot+wgt;

end if;

end do;

end do;

R(ix,iy):=top/bot;

end if;

end do;

end do;

end proc:
