+%OPTOMO Wrapper for ASTRA tomography projector
+%
+% OP = OPTOMO(TYPE, PROJ_GEOM, VOL_GEOM) generates a Spot operator OP for
+% the ASTRA forward and backprojection operations. The string TYPE
+% determines the model used for the projections. Possible choices are:
+% TYPE: * using the CPU
+% 'line' - use a line kernel
+% 'linear' - use a Joseph kernel
+% 'strip' - use the strip kernel
+% * using the GPU
+% 'cuda' - use a Joseph kernel, on the GPU, currently using
+% 'cuda' is the only option in 3D.
+% The PROJ_GEOM and VOL_GEOM structures are projection and volume
+% geometries as used in the ASTRA toolbox.
+%
+% OP = OPTOMO(TYPE, PROJ_GEOM, VOL_GEOM, GPU_INDEX) also specify the
+% index of the GPU that should be used, if multiple GPUs are present in
+% the host system. By default GPU_INDEX is 0.
+%
+% Note: this code depends on the Matlab toolbox
+% "Spot - A Linear-Operator Toolbox" which can be downloaded from
+% http://www.cs.ubc.ca/labs/scl/spot/
