What is MATLAB What is MATLAB • It is a high-performance language for technical computing. It integrates computation, visualization, and programming environment. • it is a also modern programming language environment: it has sophisticated data structures, contains built-in editing and debugging tools, and supports object-oriented programming. • It has many advantages compared to C/C++ for solving engineering problems

Examples with Examples with MatLab • For example, suppose you wanted to plot sin(2 t) • MatLab Commands >> t=-2*pi:pi/100:2*pi; >> plot(t, sin(2*t)); • the first command means that t is equal to the ordered set of numbers from –2*pi to 2*pi in increments of 0.01*pi
