Built-In Functions and help:
There are lots of built-in functions in a MATLAB. The help command is used to find out what functions MATLAB has, and how to use them. For illustration, typing help at the prompt in the Command Window will represent a list of help topics that are the groups of related functions. This is a very big list; the most elementary help topics are in the starting.
For illustration, one of these is listed as matlab\elfun; it involves the elementary math functions. The other is the first help topics as matlab\ops that shows the operators which can be used in expressions.
To see the list of functions contained within aspecific help topic, type help followed by the name of the topic. For illustration,
>> help elfun
will represent a list of elementary math functions. It is a very big list, and is broken into trigonometric (for which the default is radians, but there are equivalent functions which rather than use the degrees), complex, exponential, and rounding and remainder functions.
This can be done from the command line or from a makefile. You require a script (filename.m). Just type at the command line, or contain in the makefile: matlab
Various commands for get the help: There are various commands which can serve as an introduction to MATLAB and allow you to get the help: info will show contact informatio
I am trying to implement this equation u_t=-\u_x\ using upwind scheme. and as a second step, I need to put some stopping function g(h) where u_t=-g(h)\u_x\ how can I write this on
hey ! why the command sawtooth and square does not exist in Matlab R2012a?
Illustration of a conditional loop - While loop: As an illustration of a conditional loop, we will write a function which will find the first factorial which is greater than t
logical operators: The logical operators are as shown below: All the logical operators operate on Boolean or logical operands. The not operator is a unary operator; wh
1;write the matlab of LU decomposion that can do any n*n matrix by considering scaling and pivoting?
Use the MATLAB randn function to generate 1000 points for x. Generate the output of the unknown system with the ?lter function and b=[1232 1] and a=[1]. Normalise the ?lter output
A 12-point sequence is x (n) defined as x(n) = { 1, 2, 3, 4, 5, 6, 6, 5, 4, 3, 2, 1}. Write MATLAB programs to (a) Determine the DFT X (k) of x(n) and plot (using stem function)
Your functions will allow you to create the following graph, which contains a piecewise function where a line exists in the first interval, a parabola in the second interval, and t
