This is a Zig port of a C Program to calculate grid based differential equations and was made to learn a bit of Zig.
Build the code with zig build and optionally optimization flags as per zig build -h for instance zig build -Doptimize=ReleaseFast.
Then run the binary zig-out/bin/zigpartdiff.
Example: zig build -Doptimize=ReleaseFast && ./zig-out/bin/zigpartdiff 1 2 100 1 2 100
To understand what the arguments mean run with -h or -?.
Alternatively compile and run with zig build run -- 1 2 100 1 2 100.
