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.
Example of Printing vectors: For vectors & matrices, even though formatting cannot be specified, the disp function may be simpler to use in common than fprintf as it displays
A file houseafford.dat stores on its three lines years, median incomes and median home prices for a city. The dollar amounts are in thousands. For example, it might look like this:
Illustration of assignment statements: At that point, if the expression mynum 3 is entered, the default variable ans is used as the result of this expression is not assigned

Writing data to a File: The save function can be used to write a data from the matrix to the data file, or to append a data file. The format is as shown below: save filenam
User-Defined Functions which return a Single Value: We have seen the use of many functions in the MATLAB. We have used many built-in functions like fix, sin, abs, double, and

Output Statements: disp and fprintf: The Output statements display strings and the answers of expressions and can permit for formatting or customizing how they are exhibited.
