Imag., 36(2):467-77, February 2017](https://ieeexplore.ieee.org/document/7582547).\nThis code was inspired by the MATLAB code written by Gopal Nataraj,\nwhich can be found [here](https://github.com/gopal-nataraj/scn-dsgn).\n\n## Getting Started\nAt the Julia REPL, type `]` to enter the package prompt.\nThen type `add https://github.com/StevenWhitaker/ScanDesign.jl#v0.0.1`\nto add ScanDesign v0.0.1\n(note that `v0.0.1` can be replaced with whatever version is needed).\nHit backspace to return to the normal Julia prompt,\nand then type `using ScanDesign` to load the package.\n\n## Overview\nThe function `scandesign` provides the main functionality.\nIt takes as input an initial set of scan parameters\nand a cost function to minimize\n(as well as optional parameters for fine-grained control of the optimization).\nThe function `expectedcost` is the cost function used\nin the paper mentioned above that takes an expectation\nover a range of unknown and known parameters\nof the trace of the inverse Fisher information matrix.\nThe function `fisher` computes the Fisher information matrix\nas described in the aforementioned paper.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fstevenwhitaker%2Fscandesign.jl","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fstevenwhitaker%2Fscandesign.jl","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fstevenwhitaker%2Fscandesign.jl/lists"}
