FAQs

How to ask the user for input 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.

answer = inputdlg( prompt ) creates a modal dialog box containing one or more text edit fields and returns the values entered by the user. The return values are elements of a cell array of character vectors. The first element of the cell array corresponds to the response in the edit field at the top of the dialog box.

A = fscanf(obj,' format ') reads data and converts it according to format . format is a C language conversion specification. Conversion specifications involve the % character and the conversion characters d, i, o, u, x, X, f, e, E, g, G, c, and s.

In Python, we use the input() function to ask the user for input. As a parameter, we input the text we want to display to the user. Once the user presses “enter,” the input value is returned. We typically store user input in a variable so that we can use the information in our program.

The input() function takes a string as an argument, which is displayed to the user as a prompt. The user can then enter a value, which is returned by the input() function as a string. Since we want to perform multiplication on the input values, we need to convert them to integers using the int() function.

You can use function handles as input arguments to other functions, which are called function functions. These functions evaluate mathematical expressions over a range of values.

The input function, typed input, operates as a way for the user to assign a value to a variable. With the input command, the user can have MATLAB provide a prompt in the command window. The user is then able to respond to the prompt by entering in their input directly after the prompt in the command window.

The prompt() method displays a dialog box that prompts the user for input. The prompt() method returns the input value if the user clicks "OK", otherwise it returns null .

A prompt dialog contains a single-line textbox, a Cancel button, and an OK button, and returns the (possibly empty) text the user entered into that textbox.

What is feature input MATLAB? ›

A feature input layer inputs feature data to a neural network and applies data normalization. Use this layer when you have a data set of numeric scalars representing features (data without spatial or time dimensions). For image input, use imageInputLayer .

TF = isnumeric( A ) returns logical 1 ( true ) if A is an array of numeric data type. Otherwise, it returns logical 0 ( false ). Numeric types in MATLAB^® include: int8 , int16 , int32 , int64 , uint8 , uint16 , uint32 , uint64 , single , and double .

The input function allows you to ask a user to type some sort of information into the program and to save that information into a variable that the program can process.

Here's an example of using scanf() to read an integer value from the user and store it in a variable called num : int num; printf("Enter an integer: "); scanf("%d", &num); In this example, the %d conversion specifier tells scanf() to expect an integer input value.

Functions that take a function as an input (called function functions) expect that the function associated with the function handle has a certain number of input variables. For example, if you call integral or fzero , the function associated with the function handle must have exactly one input variable.
