Do not copy empty image data at initialization.
First version of coil summation GPU kernels.
Perform coil summation in adjoint operation.
Initialize output array dims depending on prensence of sensitivity data.
Fix way of dimension evaluation.
Adapted MATLAB Operator and functions to automatically coil summation.
Perform looping of input image in forward operation in case of available sensitivity data.
Fix coil summation error due to not initialized array values.
Fix error when no sensitivity data is present. Do not restrict dimensions.
Add warning when operator is built with sens data and only single channel data is passed in adjoint operation.
Adapted test scripts.
Fix output array init when no sens data is present. Has led to segfaults.
Check compute capability of default graphics device and set default value for atomic operation automatically.
