## Can a function have no outputs?

Relations can be written as ordered pairs of numbers or as numbers in a table of values. By examining the inputs (x-coordinates) and outputs (y-coordinates), you can determine whether or not the relation is a function. Remember, in a function each input has only one output. A couple of examples follow.

### Can a function in MATLAB have no inputs?

Need to start by hardcoding the test data into two 1D arrays. X’s are 1, 2, and 3 and y’s are 4, 5, and 8. The input parameters to the function will be void (that is, no input) and the output will be the two arrays defined in the function.

#### How do you suppress the output of a function in MATLAB?

To work around this issue, you could do the following:

- To disable the display of any figure windows you can use the MATLAB startup option “-noFigureWindows”.
- Use the “evalc” function to redirect all the output displayed on the command window to a variable.

**Are there void functions in MATLAB?**

You cannot create void* and void** types in MATLAB. MATLAB users can pass a void* return argument as input to a function that takes the appropriate void* input.

**Why can a function only have one output?**

In a function every input number is associated with exactly one output number In a relation an input number may be associated with multiple or no output numbers. This is an important fact about functions that cannot be stressed enough: every possible input to the function must have one and only one output.

## How do you find the output of a function?

### Does a function require an input?

A function is like a machine. It can take an input and spit out an output. The parameters are the input. This function-machine will give an output saying hello, and that output is based on the input, which is the name.

#### Can a function have no input parameters?

The arguments of a function (sometimes known as parameters) are the inputs. In computing, a function can have no arguments, but then it always outputs the same value.

**What is Scilab used for?**

Scilab, famous open-source scientific computation software, can be used to test algorithms or to perform numerical computations. Scilab also provides many numerical methods and is very easy to use even for people without prior programming experience.

**Which character used to suppress the output of a command in Scilab?**

Semicolons suppress the display of results, commas do not. Names of Scilab variables and functions must begin with a letter or one of the following special characters %, #, !, $,?, and the underscore .

## How do you create an empty function in MATLAB?

Use ClassName . empty(m,0) to create an m-by-0 array of the ClassName class. This function is useful for creating empty arrays of data types that do not have a special syntax for creating empty arrays, such as [] for double arrays. A = ClassName.

### What is return MATLAB?

Description. return forces MATLABĀ® to return control to the invoking program before it reaches the end of the script or function. If you call the script or function that contains return directly, there is no invoking program and MATLAB returns control to the command prompt.
