A tiny multidimensional array implementation in C similar to numpy, but only one file.

I wanted to dive into the trenches of implementing multidimensional arrays since quite some time. Finally, taking inspiration from numpy I decided to give it a go. I wanted to implement everything from ground up, and hence C was the perfect choice for it.

Working

Currently, smolar only supports N-d arrays of the float datatype. That is, every element in the N-d array will be a float. I did this because:

1. Integers can also be represented by floats (even though float takes more bytes in memory).
2. And for educational/learning purposes I just wanted to use float.
3. Support for more datatypes might be added in the future.

File structure

There is only one file: smolar.c

Everything, and I mean EVERYTHING is in that file.

To compile and run this file using clang compiler:

$ clang smolar.c -o smolar
$ ./smolar

Current progress

• Define Array structure
• Create/Init Array from shape
• Traverse Array using strides
• Ability to broadcast an array
• Elementwise addition operation
• More Unary and Binary Array operations
• Support more dtypes
• Parallelism loops in Array operations
