clc;
close all;
clear all;
t=0:0.01:10
a= inputdlg
f=0.5;
y= a*sin(2*pi*f*t)
subplot(2,1,1)
plot(t,y);
axis([-10 10 -10 10]);
title('Sine Function');
xlabel('Time axis');
ylabel('Amplitude axis')
When i put a number as 'a' and run the script it produces a sine graph. However i want the script to work when 'a' can be inputted by the user. When i use 'inputdlg' it prompts for me to place a figure however when i do the following shows up in the command line.
Error in Attuntitled2 (line 8)
y= a*sin(2*pi*f*t)

I prefer inputdlg, however you need to remembert that the output is a cell array or character vectors.
To enter an amplitude value of 42:
ac = inputdlg('Enter a value for the amplitude ')
a = str2double(ac)
produces:
ac =
1×1 cell array
{'42'}
a =
42
Put semiccolons at the end of the statements to prevent them printing to your Command Window. I did not use them here for demonstration purposes.
