fwdpp::state_matrix¶ Simplistic matrix representation of mutations This type uses std::vector<std::int8_t> to hold a matrix representing the genotypes for a set of diploids.
For a haplotype matrix of n individuals, the data represent 2n columns with a 0/1 encoding representing ancestral/derived.
For a genotype matrix of n individuals, the data represent n columns with a 0/1/2 encoding for the number of copies of the derived mutation.
The data layout is row-major (aka “C-style”) ordering, facilitating compatibility with GSL matrix types, NumPy 2D arrays, etc. Note that GSL matrices may be constructed using gsl_matrix_view_array or gsl_matrix_const_view_array for cases where a matrix of only neutral or only selected mutations is needed.
We use the 8-bit integer type to save space. In practice, one may convert (via copy) to other types for operations like regression.
- Note
This type is not constructed directly, but rather returned by other functions.
