Coordinate system used in this code \n    X=North, Y=East, Z=Down\n\nPackage Contents:\n\n    MTplot:\n        Plots the moment tensor radiation pattern in a variety of ways(for more help and commands use help MTplot)\n\n    Conversions:\n    MTconvert will convert any mt/focal plane input into all the different formats and return it as an MTresults class\n\n    There are several functions to convert the moment tensor to different formats i.e.\n        Strike, Dip and Rake, or Fault Plane Normals, or TNP axes:\n            MT2SDR:     Moment Tensor to Strike, Dip and Rake\n                MT2TNPE     Moment Tensor to T, N ,P axes and Eigenvalues\n                TP2FP       T,P axes to Fault Plane Normals\n                FP2SDR      Fault Plane Normals to Strike, Dip and Rake\n            SDR2MT:     Converts Strike, Dip and Rake to Moment Tensor\n            SDR2FP:     Converts Strike, Dip and Rake to Fault Plane Normals\n            FP2TNP:     Converts Fault Plane Normals to T, N, P axes\n            TNPE2MT:    Converts T, N, P axes and Eigenvalues to the Moment Tensor\n\n            convert2voigt:  Converts MT or C tensor to (modified) voigt form\n            voigt2MT:   Converts (modified) voigt form of MT to the 3x3 MT\n            MTC2D:  Converts MT and C to Potency Tensor\n            MT2BiAxes:  Converts MT and C to the BiAxes information of area displacement, isotropic volume and the biaxes\n            D2TNPE:     Converts D to TNPE\n            MT2Tape:    Converts MT to the Tape parameters (gamma,delta,kappa,sigma,h)\n\n    Omega: Calculates the 6-angle between two moment tensors in radians.\n\n    poissonRatio: Calculates the exact (isotropic material) or approximate poissons ratio (following Chapman and Leaney, 2011 eqs. 81a and b) for either lambda and mu or the full 21 \n                    component stiffness vector\n    isotropicC: Calculates the full 21 component stiffness vector for an isotropic lambda and mu\n\n    VTIC: Calculates the full 21 component stiffness vector for the 6 VTI stiffness parameters: C11,C12,C13,C33,C44,C66\n\n\n    Test:   Runs a test on an input using these functions to convert Strike, Dip and Rake to the MT and back, or the MT to Strike, Dip and Rake and back\n            and compares the differences.\n            Uses SDRtest and MTtest\n\n    ExampleConvert:     Example Script for running batch conversion and outputting to file.\n                            Input needs to be written by the user - dependent on format\n\n    The code needs the panel package (from mathworks central).\n            \nThere is some additional functionality designed to work well with mtfit.\n\n*N.B. This code was written as part of a PhD project and is not under active development or support.*","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdjpugh%2Fmtplot","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fdjpugh%2Fmtplot","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdjpugh%2Fmtplot/lists"}
