Hi all,

I was wondering how to simultaneously run .m matlab files (about 10 of them) from a linux terminal. I went through this link - https://www.mathworks.com/matlabcentral/answers/318764-how-to-run-two-matlab-scripts-in-parallel, but that was using functions wherein in my case I have multiple .m matlab files containing just lines of codes and no functions inside it.

I was opening up multiple terminals and using the command:

matlab -nodisplay -nosplash -nodesktop -r "run('path/to/your/script.m');exit;" | tail -n +11

to run multiple .m matlab files simultaneously but matlab keeps crashing in some cases while doing this. Any way to fix this?

Thanks,

Mahith M

matlab -batch "run('path/to/your/script.m')"

-batch already turns off display and splash and desktop and indicates that a command follows. It also specifically terminates MATLAB after the command is executed: that is written into the specifications for -batch whereas it is not specifically written into the specification for -r and historically was not guaranteed if you had an input()

mySphere.m

calculating the volume and surface area of a sphere given its radius=5

>> indicates where I have typed the line of code into the command window

% Define the radius of the sphere
radius = 5;
% Calculate the volume of the sphere
volume = (4/3) * pi * radius^3;
% Calculate the surface area of the sphere
surface-area = 4 * pi * radius^2;

volume=

523.5987

Surface area=

314.1592

myStats.m [MIN, MAX, MEAN, MEDIAN] = myStats(A)

B = 1:20;

[MIN, MAX, MEAN, MEDIAN] = myStats(B)

NIN=

1

MAX =

20

MEAN=

10.50000

MEDIAN=

10.50000

FourCorners.m

if the input A is A = [12, 11, 10, 9; 8, 7, 6, 5; 4, 3, 2, 1]

The output should be B = [12, 9; 4, 1]

function B = FourCorners(A)   
% FourCorners function extracts the four corner elements from the input array A    % and returns them in a 2x2 array B.  
% Ensure A has at least two rows and two columns    if size(A,1) < 2 || size(A,2) < 2        error('Input array A must have at least 2 rows and 2 columns.');    end        % Extract the corner elements    top_left = A(1, 1);    top_right = A(1, end);    bottom_left = A(end, 1);    bottom_right = A(end, end);        % Create the output 2x2 array B    B = [top_left, top_right; bottom_left, bottom_right];
A = [12, 11, 10, 9; 8, 7, 6, 5; 4, 3, 2, 1];
B = FourCorners(A);
B =    [12, 9, 4, 1]

myFrame.m

if the input matrix is

A = [1, 2, 3, 4, 5; 6, 7, 8, 9, 10; 11, 12, 13, 14, 15]

The output matrix should be

A_new = [0, 0, 0, 0, 0, 0, 0; 0, 1, 2, 3, 4, 5, 0; 0, 6, 7, 8, 9, 10, 0; 0, 11, 12, 13, 14, 15, 0; 0, 0, 0, 0, 0, 0, 0]

function [M_new] = myFrame(M)
    % myFrame function takes a matrix M and returns a new matrix M_new
    % that contains the original matrix surrounded by zeros.
 
    % Get the size of the original matrix
    [rows, cols] = size(M);
    
    % Create a new matrix of zeros with dimensions increased by 2 on each side
    M_new = zeros(rows + 2, cols + 2);
    
    % Place the original matrix M in the center of M_new
    M_new(2:end-1, 2:end-1) = M;
