Version 0.3

• Added equality testing. Contributed by Ryan P. Adams.
• Added flag that determines whether threads are synced after each call.
• Added direct blas calls for two elementwise operations. Contributed by Vincent Vanhoucke.
• Added the set_selected_columns. Contributed by Tijmen Tieleman.
• Added tanh, abs, and log_1_plus_exp. Contributed by Ilya Sutskever.
• Some bug fixes. Contributed by Jonathan Taylor.
• Added the select_columns method. Code contributed by Tijmen Tieleman.
• on_device should now work as intended.
• allocate_device_memory now returns an error when cublasAlloc fails.
• Fixed bug in max that showed up when an entire column was negative.
• Fixed bug in activation computations in examples/rbm_numpy.py.
• Added get_col_slice and set_col_slice methods.
• Added init and shutdown methods to shorten cublas_init and cublas_shutdown.
• Added bound checking to the various slicing methods.
• Fixed problem with pow and negative numbers.
• Added support for matrix powers in pow.

Version 0.2

• Methods add, subtract, mult, divide can now take scalars as well as instances of CUDAMatrix.
• Deprecated add_scalar, mult_by_scalar, div_by_scalar.
• Methods now return target or self to make chaining operations easier.
• Added asarray method.
• Added transpose method.
• Added sqrt and pow functions.
• Added the sigmoid method to the module level.
• Added add_row_vec.
• Added empty. Now when you don't provide a target or pre-allocated temporary storage cudamat methods will not take up CPU RAM or transfer anything between the CPU and GPU.
• Added get_row_slice and set_row_slice.
• Added less_than_scalar, greater_than, greater_than_scalar.
• Added max (axis=1 is currently not supported.)

Version 0.1.5

• Added shape attribute and reshape method.

Version 0.1

• Most methods now throw python exceptions instead of exiting after encountering an error.
• The CUDAMatrix constructor now automatically converts ndarray objects to float32 in FORTRAN order.
• Renamed scalar_mult to mult_by_scalar and scalar_div to div_by_scalar.
• Added log and exp functions.
• Removed add_row_sums and sum_rows.
