Display Function Matlab

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

Display function matlab.

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. Script files cannot have the same name as a function in the file. To show the value of a variable or to show program output in the command. This type of function must be defined within a file not at the command line.

The name of the file and of the function s. If x is an instance of a matlab class then matlab calls the display method of that class if such a method exists. For example use times instead of. Here are three ways to display multiple variable values on the same line in the command window.

Matlab calls the display function to show information about an intermediate result such as the values size type and variable name. Use disp to display the result. 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. Often you store a function in its own file.

Functions are supported in scripts in r2016b or later. Save the file either in the current folder or in a folder on the matlab search path. Concatenate multiple character vectors together using the operator. Use disp to display the result.

The semicolon ending the line stops matlab from outputting that line later. In a script file which contains commands and function definitions. The second line tells matlab to take the input square it and set the new number as the output. Line 3 tells matlab that the function has concluded.

Specify a function of the form y f x. Convert any numeric values to characters using the num2str function. Were the semicolon not used the output would display twice when we used the function later on. 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.

The name of the file must match the name of the first function in the file. To show the value of a variable or to show program output in the command. Use array operators instead of matrix operators for the best performance. 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. Matlab functions a function is a group of statements that together perform a task. Concatenate multiple character vectors together using the operator. 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. A typical implementation of display calls disp to do most of the work and looks like this. Matlab calls the display function to show information about an intermediate result such as the values size type and variable name.
