Sorry for not answering earlier.
I create a new ticket since this one is closed and don't see how to re-open
it.

Here is the script herebelow,
The problem seems to be related to the function "babu" that I am using. When I
use a string paameter to any function (can be "babu" or anything else), the
problem occurs. Looks like a memory issue. Do you see anything wrong with what
I am doing here.
I understand that in octave all function parameters are passed by value

I also tried
essai1=babu('/home/andre/clone/search-workers/image-processing/algo/set_of_images/testsethamed/Images/3.jpg');

----------------------------
function loaded = image_loader(s)
%let the user launch some matlab functions on the set of pictures realized by
hamed

l={1;2;6;9;10;12;14;15;17;19;20;21;25;26;28;29;35;44;50;57;58;59;60;61;62;63;64;65;66;67;68;69;70;71;72;73;74;75;76;77;78;79;80;81;82;83;84;85;86;87;88};

for i =1:51
a=l{[i,1]};
text=sprintf('/home/andre/clone/search-workers/image-processing/algo/set_of_images/testsethamed/Images/%d.jpg',a);
essai1=babu(text);
disp(essai1)
end
loaded=1;

-------------------------------
function Quality=babu(img)
im=imread(img);

if length(size(im))>2
y=rgb2gray(im);
else
y=im;
end

Can you upload the m-file you are using and the exact sequence at the command
line that triggers the bug so that others can try to duplicate this. It's too
vague right now for me to decide what is going on.

Hello,
My issue is linked with my build system, For some reason when I try on some
function.m file
result=function('a String')
the function returns A(I): index out of bounds; value %% out of bound %%

But if the result do not depend on the input
result=function(a number)
would work and
result=function('a String')
wouldnt with the same error A(I): index out of bounds triggered.

Moreover, I can also avoid the error by changing the name of the function and
function file by for example call the function function1 and then
result=function1('a String')
would work

So it is like my build is related to the issue and randomly create errors on
some functions that take string in input(it could be some random function with
random names). I reinstalled octave multiple time and it didn t change
anything.
Any idea on what part of octave on an ubuntu system could be related to this
kind of bug?
Thank you,
Andre Fougeront
