**undefined function or variable #8**Dear all,
I am new to matlab and got stuck with a problem---- undefined function or variable b.
could any of you help me with it? thank you very much.
my function is as follows;
function [ p ] = RT( a )
%UNTITLED2 1-dimension rapid transformation
% Detailed explanation goes here
[m,n]=size(a);
if n~=1
for i=1:n/2
b(i) = a(i) | a(i+n/2);
c(i) = xor(a(i),~a(i+n/2));
end
b=RT(b); c=RT(c);
end
p = [b,c];
end
I have a feeling that the problem may be that b=RT(b) is not correct,but I am not sure and have no idea how to fix it. thank you again!
Thank you ...

I have a m.file and the code works perfectly if I type it in the command window. Whenever I try to run the script I get the error message:

**Undefined function or variable #4**Hi,
I am trying to run a very simple function in Matlab that I have named
get_max. When I type ls or dir, I can see the function file in the
directory listing and I can open the file in the ''Current
directory'' window, but when I type get_max in the command window, I
keep getting the ''Undefined function or variable'' message. I've
tried creating a new file and copying the code to it, but it still
won't run. I really don't understand what's going on here... Thanks
for your help.

**Undefined function or variable #3**I get into trouble using a function 'apply'

So Matlab knows which 'apply' I am talking about.
But, here is the problem:

Why would this happen? Any suggestions? Is it because it resides in a
very special directory with a '@'?

Following is the Test.m

% function Test

I can not understand what happens. Is this the known bug of the matlab
?
On all other directories, matlab does not work.
I made a simple Test directory and a file shown above.
Can you tell me how can I fix this ?
The Computer is not on the network. Is this can be a reason of this
weird thing?
Thank you.
