PURPOSE ^

SAVE_AVW(img,fname,vtype,vsize)

SYNOPSIS ^

function save_avw(img,fname,vtype,vsize)

DESCRIPTION ^

 SAVE_AVW(img,fname,vtype,vsize) 

  Create and save an analyse header (.hdr) and image (.img) file
   for either a 2D or 3D or 4D array (automatically determined).
  fname is the filename (must be inside single quotes)
   
  vtype is 1 character: 'b'=unsigned byte, 's'=short, 'i'=int, 'f'=float
                        'd'=double or 'c'=complex
  vsize is a vector [x y z tr] containing the voxel sizes in mm and
  the tr in seconds  (defaults: [1 1 1 3])
