15.16  CONVOLUTE 

CONVOLUTE BY={nset|"name"} [APPEND[=ON|OFF]] [NAME="name"] [CHECK[=ON|
          OFF]] [ERROR[=ON|OFF]] [INVERT[=ON|OFF]] [LOG[=ON|OFF]]
          [MONITOR[=ON|OFF]] [NORMALIZE[=ON|OFF]]
          [SETS=[FROM] n1 [TO] [n2]] [SELECT="name"]
Convolutes nset with the specified data sets.

The specified data sets and nset must be histograms with the same spacing
between points.  If nset is a mesh, then the data sets must also be mesh
data.  You may convolute a mesh by a normal data set.

NOTE:  The inverse convolution of 2 mesh data sets may not be correct.
This problem may be fixed in the next version.
