0.4.0

New Features

• Implementation of new manipulation methods: atleast_1d, atleast_2d atleast_3d, expand_dims and append.
• Introduction of argmin and argmax methods for CPU.
• Arithmetic operations between GPU stored NDArray and CPU stored scalars.

Bug fixes

• Fixed a problem where NDArray::transpose on GPU was causing SEGFAULT.
• Increases the stability of memory management and allocation of various components through Valgrind's detailed memcheck analyses.
• Use of an expandable buffer in the NDArrays print function, avoiding excess null characters and memory waste.
• Fixed memory leaks detected by Valgrind in all components.
• Fixed an issue where the NDArray::allclose method returned an incorrect result.
• Fixed a problem where the NDArray::sinc method returned incorrect values.
• Fixed the arginfo of the NDArray::arange method that was causing mismatch.
• Changes some tests affected by changes from this MR.
• Fixed a problem where the NDArray::allclose method accepted NDArrays stored in VRAM when there was no implementation for that.
• Fixed the NDArray::all method that used AVX2 in a suboptimal way.
• Fixed an invalid memory read when NDArray::clip received a PHP array as an argument.

Others

• General code cleaning, removal of unnecessary includes, variables and allocations.
