Display Function Matlab

Use disp to display the result.

Display function matlab.

A typical implementation of display calls disp to do most of the work and looks like this. If the class has no display method or if x is not an instance of a matlab class then the matlab built in display function is called. Use array operators instead of matrix operators for the best performance. To show the value of a variable or to show program output in the command.

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. 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. The function must accept a vector input argument and return a vector output argument of the same size.

Here are three ways to display multiple variable values on the same line in the command window. Function to plot specified as a function handle to a named or anonymous function. Script files cannot have the same name as a function in the file. Functions must be at the end of the file.

The name of the file and of the function s. Concatenate multiple character vectors together using the operator. Save the file either in the current folder or in a folder on the matlab search path. In matlab functions are defined in separate files.

In a script file which contains commands and function definitions. Often you store a function in its own file. The semicolon ending the line stops matlab from outputting that line later. Use disp to display the result.

When you run the file it will display the following result. Matlab calls the display function to show information about an intermediate result such as the values size type and variable name. Were the semicolon not used the output would display twice when we used the function later on. The second line tells matlab to take the input square it and set the new number as the output.

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. Here are three ways to display multiple variable values on the same line in the command window.

Specify a function of the form y f x. If x is an instance of a matlab class then matlab calls the display method of that class if such a method exists. Concatenate multiple character vectors together using the operator. Line 3 tells matlab that the function has concluded.

Matlab calls the display function to show information about an intermediate result such as the values size type and variable name. The name of the file must match the name of the first function in the file. This type of function must be defined within a file not at the command line.
