iFit/sw_intsf

 integrates the structure factor along given Q directions

 sFact = SW_INTSF(sFact, 'Option1', Value1, ...) 

 Options:

 axis      The index of the axis, along which the data is summed within
           the given range. {1, 2, 3} is for {a*, b*, c*} respectively.
           Zero is to powder average the data. Default is 1. More than one
           axis can be given.
 range     Data range in r.l.u. along selected dimension to integrate,
           default is the full data range.
 type      Type of data to be used for the integration.
               'sf'    integrate the calculated structure factor. (default)
               'perp'  integrate the perpendicular component of the structure
                       factor to Q.

 Output:
           sFact contains the following new fields:
           int     The integrated data in a matrix.
           hklint  A cell containing the three axis vectors in r.l.u. and

 Example:
   sFact = cryst.structfact;
   sFact = sw_intsf(sFact,'axis',[1 2],'range',[0 1; 0 2]);

   The above code will integrate the structure factor along a* between 0
   and 1, along b* between 0 and 2.
