3 Dimensional Plots
Meshgridgenerates all possible x and y coordinates in a range
Editing plots
There is much, much more to learn about editing and formatting plots.
Play with the ‘property editor’Anything you can do in the property editor you can do with code.
Solving Equations
solve(equations, variable)
Systems Biology Modeling
Simulated biochemical systems using MATLAB• Test and generate hypotheses• Fewer and better experiments• Mechanistic explanation for results!• Accessible• Translational
