Hey guys,

I'd need some help from you regarding the following problem. I want the user to enter numbers in the command window ( input(prompt) ) and plot the numbers. (Inputs should be visualized as points). For example: first input should be on x-coordinate 1 , second user input should be at x-coordinate 2 and so on. The y-coordinates of each point should be represented by the number that the user enters in the command window.

clc; 
clear all; 
close all; 
x = 0:1:10;  
numberOfInputs = 0;
prompt = 'Enter any number that you like:';
%{ I only want the user to enter a maximum of 10 numbers. %}
while numberOfInputs <=10    
    
    if input(prompt) == true
        
        enteredValue = input(prompt);
        numberOfInputs = numberOfInputs + 1; 
        %plot()
    end 
end

Would really appreciate it if somebody could help me with this.

Best regards and stay safe,

Alex

在 MATLAB Online 中打开

prompt = 'Enter any number that you like:';
%{ I only want the user to enter a maximum of 10 numbers. %}
N = 10 ; 
figure
hold on
for i = 1:N       
        enteredValue = input(prompt);
        plot(i,enteredValue,'s')
end
