Ok, maybe you though the question is not meaningful, sorry for that.
the problem is: I want to deal with a time series images,each image is
2300*1500 pixels, there are 300 images in total. so I have to define a
array 2300*1500*300 to store all pixels. there is no problems till
now, the problem is : each pixel at each time point have its own
ancillary data, these ancillary information are essential for process
the pixel values through time and space axises.
and, for my limited knowledge about IDL, I have to define another four
array to store these ancillary data. the error appears when I define
an extra array to store the values after all processing steps....
you could image my embarrassing situation.
all i want to know is whether there is an way to store these
information without any memory allocation, does Pointer help?
Thanks again.
