idlwrap API

idlwrap helps you port IDL code to python by providing an IDL-like interface to numpy and scipy.

• API

Note

• Array
  • IDL a[i, *] is the same as Python a[:,i] There are two different ways of storing a matrix/array in memory: column-major and row-major.
  • IDL array index include the last element:

    IDL> (FLTARR(10))[3:5]
     0.00000      0.00000      0.00000 ; -> three elements
    

    >>> np.zeros(10)[3:5]
    array([0., 0.]) # -> two elements
