=============
First step:
I need to build a ut=dblarr(36000,500,25) in IDL's pro---sfit.pro.
And then continue:
==================
;kk = invert(ut#transpose(ut))#ut ==>
kk=transpose(ut)
kk=ut#temporary(kk)
kk=invert(temporary(kk))
kk=temporary(kk)#ut
kx=float(temporary(kk)#reform(irreg?zz:z,m,1))
if max_deg eq 0 then kx = reform(kx, degree+1, degree+1)
return, irreg ? reform(reform(kx,n2) # ut, m):
reform(reform(kx,n2) # ut, nx, ny)
==============================================
Who can help me?
Under Mark's help,I already changed my swap.But it seems that IDL does
not see /dev/hda9 having enough space and gives up its working.
