# How do you get multiple inputs from user in MATLAB?

## How do you get multiple inputs from user in MATLAB?

1. If the values are all of the same numeric type, the user can enter them with [] around the list.
2. If the values are not all the same type, or are string type, then the user can enter a cell array.

How do you write a function with two inputs?

To create a function with two inputs, we just need to provide two different arguments inside function. For example, if we want to create a function to find the square of a+b then we can use x and y inside function.

### Can there be two inputs for one output?

Unless your definition of “function” is quite unusual, the answer is no, just by definition. This is legit, but it’s a so called relation, not a function. By (informal) definition functions are a special kind of relations allowing precisely one output for each input.

Can a function have 2 outputs?

A vector space may have multiple dimensions, but a vector is still a single value in that space. Consider for example that any complex function f:C→C has as “output” a complex number z, which can also be regarded as a real (x,y) pair. A function has just one output, but this output may have many dimensions.

## What does double function do in Matlab?

double (MATLAB Functions) double(x) returns the double-precision value for X . If X is already a double-precision array, double has no effect.

How do you make an input function in Matlab?

x = input( prompt ) displays the text in prompt and waits for the user to input a value and press the Return key. The user can enter expressions, like pi/4 or rand(3) , and can use variables in the workspace. If the user presses the Return key without entering anything, then input returns an empty matrix.

### How many outputs can a function have in MATLAB?

You cannot pass more than one (1) argument out of a function that is used in the MATLAB FCN block. If you need to pass more than one variable out of a function, you will have to concatenate all variables into one vector, and pass that vector out of the function.

How many inputs can a function have?

Remember that in a function, the input value must have one and only one value for the output. There is a name for the set of input values and another name for the set of output values for a function. The set of input values is called the domain of the function.

## Why can’t a function have two outputs?

A function has one output for every input because something that doesn’t is not a function. It’s the set {1, 2}. What you have here is a multivalued function (or, more generally, a relation), and the definition of a function f used to allow multiple values of f(x) for the same x.

Can inputs repeat in a function?

A function is a special kind of relation. In a function, there can only be one x-value for each y-value. There can be duplicate y-values but not duplicate x-values in a function.

### Why can’t a function have 2 outputs?

No; functions are relations between an input and a single output. It is like a machine where something goes in, and then only one thing comes out, and it only depends on the input. That is . A relation between two sets is a collection of ordered pairs and we use the notation to mean that .

What does subs do in MATLAB?

subs replaces the values in the symbolic function formula, but does not replace input arguments of the function. Replace the arguments of a symbolic function explicitly.

## What are the functions of MATLAB?

– Variables – Vectors and matrices – Structures – Functions – Function handles – Classes and object-oriented programming

How do you use function in MATLAB?

Define x,by specifying the range of values for the variable x,for which the function is to be plotted

• Define the function,y = f (x)
• Call the plot command,as plot (x,y)
• ### How to write function in MATLAB?

Open up MATHWORKS MATLAB and press the New Script button.

• Type the inputs of your function in between the parenthesis.
• Comment on what each input is.
• Type in the operation you want your program to do using your inputs.
• Use an fprintf statement to output the result of your equation.
• Decide on what you want your message to display.
• How to get multiple outputs from a function?

– Returning multiple values Using References: We use references in C++ to store returned values. – Returning multiple values using Class and Object : The idea is similar to structures. – Returning multiple values using STL tuple : The idea is similar to structures.
