MATLAB provides some special expressions for some mathematical symbols, like pi for π, Inf for ∞, i (and j) for √-1 etc.Nan stands for 'not a number'. Use of Semicolon (;) in MATLAB Semicolon (;) indicates end of statement. However, if you want to suppress and hide the MATLAB output for an expression, add a semicolon after the expression.

MATLAB cycles through a prede ned set of colors to distinguish between the multiple plots. hold on This is used to add plots to an existing graph. When hold is set to on, MATLAB does not reset the current gure and any further plots are drawn in the current gure.

\Introduction to MATLAB for Engineering Students" is a document for an introductory course in MATLAB°R 1 and technical computing. It is used for freshmen classes at North-western University.

•In MATLAB, the index of the first element in a vector is 1. You can access an element by providing the index within the parenthesis after the variable name. •Instead of using a number as an index directly, you can use a variable that contains a number as an index.

MATLAB i About the Tutorial MATLAB is a programming language developed by MathWorks. It started out as a matrix programming language where linear algebra programming was simple. It can be run both under interactive sessions and as a batch job. This tutorial gives you aggressively a gentle introduction of MATLAB programming language.

2D Plotting with Matlab Matlab has powerful plotting functions which make visualizing functions easy. Let’s consider the function f1 x( ) =3x +4 1. If you were to plot this by hand on graph paper, you would probably follow a procedure such as a. Choose a series of x values where you would like to evaluate the function. b.

Matlab is a column vector based language, load memory columnwise rst always. For faster code also prealocate memory for variables, Matlab requires contiguous memory usage!. Matlab uses copy-on-write, so passing pointers (adresses) to a function will not speed it up. Change variable class to potentially save memory (Ram) using:

12. MATLAB Functions MATLAB Functions are similar to functions in Fortran or C. They enable us to write the code more efficiently, and in a more readable manner. The code for a MATLAB function must be placed in a separate .mfile having the same name as the function. The general structure for the function is

Matlab switches into the scope of the function, getting ready to execute the code inside it. All variables outside the function become invisible to Matlab, so there can be no conflict between the caller’s and callee’s variables, even if they share the same name. Despite being invisible, all of the caller’s variables persist in Matlab’s ...
