> I just change the dimensions of my array before. The above are the original one

Yes, you will have to alter my example to fit your data.

In my example, X is originally a 301 element array:

x = indgen(1,301)

In order to add X to Bx and to access SIM and DIM (which are 301x301 arrays), I converted X to a 301x301 array. This allowed me to eliminate FOR loops.

x = lindgen(1,301)
x = round(rebin(x, 301, 301) + Bx)

The error that you mention usually is a result of comparing an array to a scalar

IDL> if bytarr(348,348) eq 0 then print, 'No Error'
% Expression must be a scalar or 1 element array in this context: <BYTE Array[348, 348]>.
