This tutorial gives you aggressively a gentle introduction of matlab programming language.

By default, matlab clears the figure each time you call a plotting function, resetting the axes and other elements to prepare the new plot. If you are using an earlier release, use the subplot function instead. Matlabs programming interface gives development tools for improving code quality, maintainability, and maximizing performance. In this example, we will draw two graphs with the same function, but in second time, we will reduce the value of increment. Create axes in tiled positions matlab subplot mathworks.
