 Working with matrices in MATLAB. MATLAB has many useful commands for creating, manipulating or operating on matrices. I hope to show you just a small. This example shows basic techniques and functions for working with matrices in the MATLAB® language. Matlab "thinks" in vector's and matrices, and it is most efficient if Matlab users treat every variable as a vector or a matrix. I will followup on this latter. We will start.

Matrices and Arrays - MATLAB & Simulink

Jack Littlean engineer, was exposed to it during a visit Moler made to Stanford Matrices in matlab in Recognizing its commercial potential, he joined with Moler and Steve Bangert. It is now also used in education, in particular the teaching of linear algebranumerical analysisand is popular amongst scientists involved in image processing.

Values can come from constantsfrom computation involving values of other matrices in matlab, or from the output of a function. That is, the array starts at 1 the initial valueincrements with each step from the previous value by 2 matrices in matlab increment valueand stops once it reaches or to avoid exceeding 9 the terminator value.

Matrices can be defined by separating the elements of a row with blank space or comma and using a semicolon to terminate each row. Undefined function or matrices in matlab a.

Other operations include finding an approximation to the eigen values of a matrix. There are two versions of this routine, one just finds the eigen values, the other finds both the eigen values and the eigen vectors.

If you forget which one is which, you can get more information by typing help eig at the matlab prompt. Matlab has special commands that will do this for you. Before finding the approximations to linear systems, it is important matrices in matlab remember that if A and B are both matrices, then AB is not necessarily equal to BA.

Examples of their use are given below. Of the many possible vectorization techniques, many rely on MATLAB indexing methods, five of which are described in this article. Indexing Vectors Let's start with the simple case of a vector and a single subscript. You can always, however, use a scalar on the right side: Matrices in matlab Matrices with Two Subscripts Now consider indexing into a matrix.

MATLAB - Matrix

We'll matrices in matlab a magic square for our experiments: The simplest form just picks out a single element: For example, suppose you want to extract the 2,13,2and 4,4 elements from A. The expression A [2 3 4], [1 2 4] won't do what you want.

This diagram illustrates how two-subscript indexing works:
