ECE103 Spring 2008 Lecture 4 Basic use of MATLAB ® We will introduce the very basic concepts using a powerful software package called MATLAB. This is a high performance language that integrates computation, visualization and programming. MATLAB stands for matrix laboratory. The program easily handles matrixes and vectors and has a powerful graphic package to display magnitudes in 2D and 3D. MATLAB language is specially oriented to calculations with vectors and matrixes and to perform these calculations it is straightforward. Let us go with an example. When you run the program a command window will appear. It is possible to customize the arrangement of the desktop, and the figure is one possibility. The right side window is the command window and this is the place where we will write the instructions. The left side window will keep track of all defined variables and its dimensions. MATLAB operations are designed to work with matrixes. Special cases are 1x1 matrixes (scalars) or matrixes with only one row or column (vectors).

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
