CPU usageJacket only contains GPU computing functions. To run functions on the CPU, try one of the MathWorks products:

Notes

  • / - Matrix Right Divide (MRDIVIDE) - B is restricted to scalars.
  • \ - Matrix Left Divide (MLDIVIDE) - Does not support empty inputs.
  • \ - Matrix Left Divide (MLDIVIDE) - For M<N, CPU-based MATLAB returns a solution with the maximum number of trailing zeros. On the other hand, the LAPACK function SGELS returns a minimum norm solution, which is what Jacket returns for MLDIVIDE on the GPU. Therefore, it is important to adjust for this difference as needed.
  • ^ - Matrix Power (MPOWER) - Inputs must be non-sparse and square. The power must be a MATLAB scalar.
  • With Base Jacket, MLDIVIDE and MPOWER are supported for real, single inputs only. MPOWER is supported for positive powers only.
  • With Jacket DLA, MLDIVIDE and MPOWER are supported for single and double precision and for real and complex inputs. MPOWER is supported for positive and negative powers.
  • With Jacket SLA, MTIMES, TRANSPOSE and CTRANSPOSE are supported for sparse matrices.
    • MTIMES is only supported for A * B when A is sparse, B is dense.
  • Check out some MTIMES benchmarks using Jacket
  • When used with GCOMPILE all arithmetic operations are performed element-wise.
