The second line tells matlab to take the input square it and set the new number as the output.
Display function matlab.
Matlab functions a function is a group of statements that together perform a task.
For example use times instead of.
To show the value of a variable or to show program output in the command.
Convert any numeric values to characters using the num2str function.
A typical implementation of display calls disp to do most of the work and looks like this.
Display x is called by matlab when a statement or expression is not terminated by a semicolon omitting the terminating semicolon from a statement or expression displays a result.
Line 3 tells matlab that the function has concluded.
Here are three ways to display multiple variable values on the same line in the command window.
Functions are supported in scripts in r2016b or later.
Display x is called by matlab when a statement or expression is not terminated by a semicolon omitting the terminating semicolon from a statement or expression displays a result.
The function must accept a vector input argument and return a vector output argument of the same size.
Matlab calls the display function to show information about an intermediate result such as the values size type and variable name.
This type of function must be defined within a file not at the command line.
If x is an instance of a matlab class then matlab calls the display method of that class if such a method exists.
Use array operators instead of matrix operators for the best performance.
Concatenate multiple character vectors together using the operator.
In matlab functions are defined in separate files.
Script files cannot have the same name as a function in the file.
Functions must be at the end of the file.
Concatenate multiple character vectors together using the operator.
Were the semicolon not used the output would display twice when we used the function later on.
The name of the file and of the function s.
Often you store a function in its own file.
Use disp to display the result.
The name of the file must match the name of the first function in the file.
Specify a function of the form y f x.
Convert any numeric values to characters using the num2str function.
When you run the file it will display the following result.
Function to plot specified as a function handle to a named or anonymous function.
Save the file either in the current folder or in a folder on the matlab search path.
Here are three ways to display multiple variable values on the same line in the command window.
To show the value of a variable or to show program output in the command.
The semicolon ending the line stops matlab from outputting that line later.
Use disp to display the result.
In that case the best practice is to use the same name for the function and the file in this example fact m since matlab associates the program with the file name.
