Ionic model example in Matlab

Description

• This example will guide you through running a simple ionic model (Beeler-Reuter) in Matlab

Run the model

• Start the Matlab application
• Download the following Matlab files into a single separate folder

  • All four files as a zip package: (rebeelerreuter.zip)

  • Each file separately: (BR_2.m), (BR_deriv_std.m), (BR_deriv_vts.m), (RK4.m)

• File→Set Path…→Add Folder…
  • Navigate to the folder created in the last step, and add that path

• In the Matlab command window, type BR_2 (elapsed time will be printed when it is finished running)

• Create plots by typing in the following commands

  • plot(t,Vm): plots the transmembrane potential

  • plot(t,Ca_i): plots the intracellular Ca2+

  • plot(t,i_Na): plots the Na+ current

  • plot(t,i_Ca): plots the Ca2+ current

  • plot(t,i_K1): plots the K+ current

  • plot(t,i_x1): plotd another K+ current
