Questions and Answers

What is the output format of the command 'fprintf('%s will be %d this year. ', name, age);' when name is 'Alice' and age is 12?

  • Alice is 12 years old.
  • Alice will be 12 this year.
  • Alice will be 13 this year. (correct)
  • Alice will be 11 this year.

    • In the provided code snippet, how does the program determine if a number is odd or even?

  • By comparing the number directly to zero.
  • By inputting the age and using it as an indicator.
  • By checking if the number is less than 0.
  • By using the modulus operator % to divide the number by 2. (correct)

    • What will be the output if the variable 'x' is set to -3 in the if statement 'if x < 0'?

  • Positive
  • Negative (correct)
  • Even number
  • Error: number must be positive.

    Study Notes

    MATLAB Modeling and Simulation

    • MATLAB is a software used for numerical computation and visualization.
    • MATLAB has two types of program files: scripts and functions.
    • Scripts are a series of commands that are executed together and operate on data in the workspace.
    • Functions can accept inputs and return outputs, with internal variables local to the function.
    • The menu function displays a figure window with pushbuttons representing options.

    Objectives

    • Construct MATLAB scripts
    • Create user-defined functions that return a single value.
    • Identify and use MATLAB basic input and output commands.
    • Construct MATLAB scripts with selections and looping.

    Subtopic 1: Input and Output

    • input() lets users type in integer and string data.
    • fprintf() displays formatted text or data.

    Toolstrip and Editor

    • Scripts are stored in files with an .m extension.
    • The MATLAB editor includes features for running, editing, and saving code (e.g., clear commands, run and time).

    M Files

    • MATLAB permits script and function files (ending with .m).
    • Scripts execute commands sequentially without input parameters or outputs.
    • Functions accept inputs, perform calculations, and can return outputs.

    Example of Scripts

    • Scripts execute commands sequentially.
    • Examples include calculating area (rectangle, square, triangle, and circle).
    • Using disp() displays data without the variable identifier.
    • fprintf() displays formatted output.

    Examples of Scripts (continued)

    • Scripts can include strings and arrays (vectors, matrices).
    • Demonstrate basic calculations and operations.
    • Examples of using input functions to get user input through prompts.
    • Provide examples of output commands (disp, fprintf) for displaying data.
    • Includes examples of vectors and matrices.

    Selection and Looping Statements

    • IF statements help establish conditions for code execution based on a Boolean value.

    • Example demonstrates implementing conditional logic within a for loop (and examples of code for negative and positive values).

    • Demonstrates switch statements, a tool for selecting from different options.

      • For example different outputs based on variable values (grade).

    • For loops for iterating over a range of values.

    • Demonstrates handling different kinds of loop conditions (e.g., for, while loop syntax, range parameters, break statements).

    The Menu Function

    • The menu function prompts the user for input, displaying a list of options from which to choose.
    • Demonstrates user interaction using buttons based on the choices.

    Input and Output Commands

    • disp displays an array or string.
    • fscanf reads formatted data from a file.
    • format controls the format of display.
    • fprintf displays formatted output to the screen or a file
    • input gets user input from the keyboard.
    • A semicolon ; suppresses the screen printing.

    Input and Output Format Codes

    • %s: String
    • %d: Integer
    • %f: Floating-point number
    • %e: Floating point in scientific notation
    • \n: Newline
    • \t: Tab
