Calculate sqw for a model scattering function >> wout = disp2sqw_eval(win,dispreln,pars,fwhh,opt) Input: ------ win Dataset, or array of datasets, that provides the axes and points for the calculation dispreln Handle to function that calculates the dispersion relation w(Q) and spectral weight, s(Q) Must have form: [w,s] = dispreln (qh,qk,ql,p) where qh,qk,ql Arrays containing the coordinates of a set of points in reciprocal lattice units p Vector of parameters needed by dispersion function e.g. [A,js,gam] as intensity, exchange, lifetime w Array of corresponding energies, or, if more than one dispersion relation, a cell array of arrays. s Array of spectral weights, or, if more than one dispersion relation, a cell array of arrays. More general form is: [w,s] = dispreln (qh,qk,ql,p,c1,c2,..) where p Typically a vector of parameters that we might want to fit in a least-squares algorithm c1,c2,... Other constant parameters e.g. file name for look-up table. pars Arguments needed by the function. Most commonly, a vector of parameter values e.g. [A,js,gam] as intensity, exchange, lifetime. If a more general set of parameters is required by the function, then package these into a cell array and pass that as pars. In the example above then pars = {p, c1, c2, ...} fwhh Full-width half-height of Gaussian broadening to dispersion relation(s) 'all' [option] Requests that the calculated sqw be returned over the whole of the domain of the input dataset. If not given, then the function will be returned only at those points of the dataset that contain data. Applies only to input with no pixel information - it is ignored if full sqw object. 'ave' [option] Requests that the calculated sqw be computed for the average values of h,k,l of the pixels in a bin, not for each pixel individually. Reduces cost of expensive calculations. Applies only to the case of sqw object with pixel information - it is ignored if dnd type object. Output: ------- wout Output dataset or array of datasets

- disp2sqw_eval Calculate sqw for a model scattering function
- sqw Convert input dnd-type object into sqw object
