This document discusses MATLAB commands for plotting graphs and formatting text output. It introduces: 1) Format specifiers like %s, %c, %d, %f for printing strings, characters, integers, and floating point numbers. 2) Commands like \n, \t for new lines and tabs when printing. 3) A for loop example to print the square root and integer of numbers from 1 to 10. 4) Plotting sin and cos graphs in 2D using different colors and line styles. 5) Using subplot to display multiple graphs in a figure. 6) Creating 3D line and mesh plots with labels and titles.
