Run script Matlab Online

Hi, I have a behavioral experiment programmed as a Matlab script. I can run it on Matlab Online by logging in. Is it possible to make this public so anyone can run it via the web and Matlab Online? I just want them to be able to run the script. Or is it necessary for them to have a Matlab license of their own in order to run it?

@Tuan Pham what do you mean by "x=1"? Do you have a question?

Answer 1

[Walter Roberson]

You would have to compile it and make the executable available, or you would have build the executable into a web site and make it available that way.

[Tobias Johansson]

Ok. Thanks.

Answer 2

#% The ; denotes we are going back to a new row.
A = [1, 2, 3; 4, 5, 6; 7, 8, 9; 10, 11, 12]

#% Initialize a vector 
v = [1;2;3] 

#% Get the dimension of the matrix A where m = rows and n = columns
[m,n] = size(A)

#% You could also store it this way
dim_A = size(A)

#% Get the dimension of the vector v 
dim_v = size(v)

#% Now let's index into the 2nd row 3rd column of matrix A
A_23 = A(2,3)

This does not appear to be an answer to the question that was asked?

The comment style is not correct for MATLAB; MATLAB does not use # for comments.

Answer 3

[Tashfiq Mohsin]

%a
HF =18;
HEG=105;
C=4;
fs= 20*HEG+100;
t = 0:1/fs:1-1/fs;
signal = HF * sin(2*pi*HEG*t + pi/C);
plot(t,signal);
axis([0 0.02 20 20]);

Error using matlab.graphics.axis.Axes/set
Value must be a 1x2 vector of numeric type in which the second element is greater than the first element or is Inf.

Error in axis>LocSetLimits (line 292)
set(ax,...

Error in axis (line 113)
LocSetLimits(ax(j),cur_arg,names);

[Walter Roberson]

If you wanted y to be permited to show negative 20 to +20 then

axis([0 0.02 -20 20]);

I need to put my ID: 18-37434-1

Consider this id: AB-CDEFG-H, need to put above id no, in this. Could you sahre me the m. file.

[Walter Roberson]

Your ID with - in it would be a character vector. Index into it to get digit characters. Arrange appropriate vectors of the characters for things like HEG, and str2double to get a number

HEG = str2double(ID([10,6,8]))

Answer 4

[nivedha manoj]

% Read an Image in MATLAB Environment

img=imread('Phone storage/Download/.jpg');

% Convert image to grayscale image

1. if read image is an RGB image img=rgb2gray(img);

% Show histogram of image

1. using imhist() functionimhist(img);

[Walter Roberson]

Unfortunately I seem to be missing the concept in your Answer that would assist someone in deploying MATLAB code as a web page?

Answer 5

[Devisha Tiwari]

x = 0 : 0.1 : 1;
y = x. ∧ 2;

Invalid text character. Check for unsupported symbol, invisible character, or pasting of non-ASCII characters.

avg_y = y(1 : length(x) − 1) + dif f (y)/2; 
K = sum(dif f (x). ∗ avg_y)

[Devisha Tiwari]

a = 0; b = 3; n = 20; 
h = (b − a)/n;

Invalid text character. Check for unsupported symbol, invisible character, or pasting of non-ASCII characters.

x = a : h : b;
y = x · ∧2;
h ∗ trapz(y)

[Walter Roberson]

In your line

h = (b − a)/n;

you accidentally used the Unicode U+2212 "Minus sign" instead of the dash character U+002D

[Walter Roberson]

In your line

y = x. ∧ 2;

you have accidentally used the Unicode U+2227 "Logical And" character instead of the Unicode U+005E "Circumflex accent" character
