+/* clog: Extremely simple logger for C.
+ *
+ * Features:
+ * - Implemented purely as a single header file.
+ * - Create multiple loggers.
+ * - Four log levels (debug, info, warn, error).
+ * - Custom formats.
+ * - Fast.
+ *
+ * Dependencies:
+ * - Should conform to C89, C++98 (but requires vsnprintf, unfortunately).
+ * - POSIX environment.
+ *
+ * USAGE:
+ *
+ * Include this header in any file that wishes to write to logger(s).  In
+ * exactly one file (per executable), define CLOG_MAIN first (e.g. in your
+ * main .c file).
+ *
+ *     #define CLOG_MAIN
+ *     #include "clog.h"
+ *
+ * This will define the actual objects that all the other units will use.
+ *
+ * Loggers are identified by integers (0 - 15).  It's expected that you'll
+ * create meaningful constants and then refer to the loggers as such.
+ *
+ * Example:
+ *
+ *  const int MY_LOGGER = 0;
+ *
+ *  int main() {
+ *      int r;
+ *      r = clog_init_path(MY_LOGGER, "my_log.txt");
+ *      if (r != 0) {
+ *          fprintf(stderr, "Logger initialization failed.\n");
+ *          return 1;
+ *      }
+ *      clog_info(CLOG(MY_LOGGER), "Hello, world!");
+ *      clog_free(MY_LOGGER);
+ *      return 0;
+ *  }
+ *
+ * The CLOG macro used in the call to clog_info is a helper that passes the
+ * __FILE__ and __LINE__ parameters for you, so you don't have to type them
+ * every time. (It could be prettier with variadic macros, but that requires
+ * C99 or C++11 to be standards compliant.)
+ *
+ * Errors encountered by clog will be printed to stderr.  You can suppress
+ * these by defining a macro called CLOG_SILENT before including clog.h.
+ *

+%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/

+% This sample illustrates the use of opTomo.
+%
+% opTomo is a wrapper around the FP and BP operations of the ASTRA Toolbox,
+% to allow you to use them as you would a matrix.
+%
+% This class requires the Spot Linear-Operator Toolbox to be installed.
+% You can download this at http://www.cs.ubc.ca/labs/scl/spot/
+
+% load a phantom image
+im = phantom(256);
+% and flatten it to a vector
+x = im(:);
+
+%% Setting up the geometry
+% projection geometry
+proj_geom = astra_create_proj_geom('parallel', 1, 256, linspace2(0,pi,180));
+% object dimensions
+vol_geom  = astra_create_vol_geom(256,256);
+
+%% Generate projection data
+% Create the Spot operator for ASTRA using the GPU.
+W = opTomo('cuda', proj_geom, vol_geom);
+
+p = W*x;
+
+% reshape the vector into a sinogram
+sinogram = reshape(p, W.proj_size);
+imshow(sinogram, []);
+
+
+%% Reconstruction
+% We use a least squares solver lsqr from Matlab to solve the 
+% equation W*x = p.
+% Max number of iterations is 100, convergence tolerance of 1e-6.
+y = lsqr(W, p, 1e-6, 100);
+
+% the output is a vector, so we reshape it into an image
+reconstruction = reshape(y, W.vol_size);
+
+subplot(1,3,1);
+imshow(reconstruction, []);
+title('Reconstruction');
+
+subplot(1,3,2);
+imshow(im, []);
+title('Ground truth');
+
+% The transpose of the operator corresponds to the backprojection.
+backProjection = W'*p;
+subplot(1,3,3);
+imshow(reshape(backProjection, W.vol_size), []);
+title('Backprojection');
