Example b132 - HMT Cardiac Mechanics Model This example solves the HMT model for a single cell. It outputs each of the state variables (Vm, Cai, Cab, lambda, To, T, z) to a UnEMAP signal file. This example also uses a time variable to set two time varying boundary conditions - namely the time course of the extension ratio (lambda) and the value of the intracellular Ca++ concentration.
