Saving your Matlab sessions

matlabtutorials — Thu, 25 Mar 2010 23:51:31 +0000

Often one wants to save the data or variables to another occasion. Maybe one wants to save the whole Matlab session. This can be done. Commands are put in a m-file but data or variables are stored in a mat-file (binary file) which can be opened with Workspace Browser. First have a look in the workspace to find out how your varables look like. Then save these in a mat-file. Read More

Localize minima and maxima of functions

Let us try to find the local minima and maxima for the function func(x). The interval of interest is [-6 0]. The algorithms are iterative. There are 2 methods to use. The first one decides x in a given interval, and the second one looks for x around an initial guess. To decide the maxima we are looking for an x that minimizes the negative function: -func(x).

Controlling Command Window Input and Output

The format Function

The format function controls the numeric format of the values displayed. The function affects only how numbers are displayed, not how MATLAB software computes or saves them. Here are the different formats, together with the resulting output produced from a vector x with components of different magnitudes. Read More

Manipulating Matrices

Matrices and Magic Squares

In MATLAB, a matrix is a rectangular array of numbers. Special meaning is sometimes attached to 1-by-1 matrices, which are scalars, and to matrices with only one row or column, which are vectors. MATLAB has other ways of storing both numeric and nonnumeric data, but in the beginning, it is usually best to think of everything as a matrix. The operations in MATLAB are designed to be as natural as possible. Where other programming languages work with numbers one at a time, MATLAB allows you to work with entire matrices quickly and easily. A good example matrix, used throughout this book, appears in the Renaissance engraving Melancholia I by the German artist and amateur mathematician Albrecht Dürer. Read More

When you start MATLAB, the MATLAB desktop appears, containing tools (graphical user interfaces) for managing files, variables, and applications associated with MATLAB.
The first time MATLAB starts, the desktop appears as shown in the following illustration, although your Launch Pad may contain different entries. Read More
