Fast, codegen-compatible functions to build piecewise polynomial 1D interpolants of column-major data, and to evaluate, integrate, or differentiate them.
Linear, PCHIP, and Modified Akima interpolants are provided.
These functions efficiently work on every column of their inputs, and handle cases where an input has only one column (without internally expanding that variable). Each column is handled separately inside a for loop. This can be executed quickly by turning these functions into MEX functions via code generation -- although they are fairly fast in MATLAB R2015b and later owing to the JIT compiler. Evaluation is done using a fast binary search.
