Polynomials

Folder with scripts and data describing muscle-tendon lengths, velocities, and moment arms using polynomial expressions of joint positions and velocities.

1. Scripts:
   1. polynomialCoefficientEstimation_main.m
      • Script that sets the process of calibrating the polynomial coefficients.
   2. polynomialCoefficientEstimation.m
      • Function that calibrates the polynomial coefficients.
   3. n_art_mat_3.m and n_art_mat_3_cas_SX.m
      • Functions that provide the polynomials based on the number of degrees of freedom and the polynomial order.
      • n_art_mat_3_cas_SX.m is derived from n_art_mat_3.m and adjusted for use with CasADi.
2. Data:
   1. muscle_spanning_joint_INFO_subject1.mat
      • Helper matrix indicating which muscle actuates which degree of freedom.
   2. MuscleInfo_subject1.mat
      • Structure with polynomial coefficients.
