<p></p> <p><b>New page</b></p><div>This function will rebin an [[IXTdataset_2d]] object along both the x and y dimensions according to the supplied optional arguments to give an [[IXTdataset_2d]] object result. The four possible optional arguments are defined as follows:<br /> <br /> <br /> *Xref is an [[IXTdataset_2d]] object, if it is supplied then the dataset_1d object will be rebinned along the x dimension according to the binning of Xref<br /> *Xdesc is an array of bin boundaries and intervals along the x dimension with a simple and more general form.<br /> **basic form (xlo,dx,xhi)<br /> ***dx &gt; 0 constant bin width = dx<br /> ***dx &lt; 0 logarithmic binning x(m+1) = x(m) *(1+|dx|)<br /> ***dx = 0 retain original bin boundaries<br /> **general form (x_1,dx_1,x_2,dx_2,...,x_n,dx_n,x_n+1)<br /> ***dx_i &gt; 0 constant bin width = dx_i<br /> ***dx_i &lt; 0 logarithmic binning x(m+1) = x(m) *(1+|dx_i|)<br /> ***dx_i = 0 retain original bin boundaries<br /> *Yref is an [[IXTdataset_2d]]object, if it is supplied then the dataset_2d object will be rebinned along the y dimension according to the binning of Yref<br /> *Ydesc is an array of bin boundaries and intervals along the y dimension with a simple and more general form.<br /> **basic form (ylo,dy,yhi)<br /> ***dy &gt; 0 constant bin width = dy<br /> ***dy &lt; 0 logarithmic binning y(m+1) = y(m) *(1+|dy|)<br /> ***dy = 0 retain original bin boundaries<br /> **general form (y_1,dy_1,y_2,dy_2,...,y_n,dy_n,y_n+1)<br /> ***dy_i &gt; 0 constant bin width = dy_i<br /> ***dy_i &lt; 0 logarithmic binning y(m+1) = y(m) *(1+|dy_i|)<br /> ***dy_i = 0 retain original bin boundaries<br /> <br /> <br /> <br /> ===F90 syntax===<br /> <br /> <br /> &lt;pre&gt;use IXMdataset_2d<br /> <br /> type(IXTdataset_2d):: input_d2d, result_d2d<br /> type(IXTstatus)::status<br /> !optional arguments<br /> type(IXTdataset_2d):: Xref,Yref<br /> real(dp)::Xdesc(:),Ydesc(:)<br /> :<br /> :<br /> ! there are 4 different permutations for the calling of IXFrebin_xy_dataset_2d.
