-_Note: As of version 0.5.0, the crate structure has changed. In order to accomodate std::Vec, the crate has been partitioned to "core" and "vec". By default, no-std is enabled with zero heap allocations. These modules live in "core". An optional feature "vectors" can be enabled to access modules in "vec" that use std::Vec instead of rust static arrays. For the difference in usage, consult the test examples. To use the vectors feature, paste this in your Cargo.toml:_
-
-```toml
-[dependencies]
-multicalc = {version = "*", features = ["vectors"] }  #Replace "*" with version number
-```
