arrays and polyfit [message #6742]

I would like to use polyfit with an array like arr1(n,n,9) and arr2(9) instead
of using it with arr1(9) and arr2(9).
Well now I must employ a FOR statement what slows my application. My actual
code is :
;arr1 = FLTARR(256, 256, 9)
;arr2 = FLTARR(9)

FOR i=0,n-1 DO BEGIN
FOR j=0,n-1 DO BEGIN
result = POLYFIT(arr1(i,j,*),arr2(*),yfit,1)
table(i, j) = result(1) ;I only want the slope
END
END

Is there a way to avoid this ??
Thanks
