realy bad problem with MatLab

Maxim — Fri, 02 May 2008 16:10:06 -0400

Can ANYBODY explain me why when I create the following
script:

a=1

in MATLAB R2007b, and call the script b.m and execute from
command window

>> b

I receive this error:

??? Undefined function or variable 'b'.

What does this idiocy mean???

That doesn't happen to me in R2007a; I don't have R2007b installed
to check with.

Where did you put b.m ? If you happened to put it in a toolbox
directory, then matlab will not find it until you issue the appropriate
'rehash' command varient.

The error message is a simple one. Matlab
does not know what b is, since it does not
find something called b.m, nor have you
defined a variable with the name b.

That it is idiocy is a subjective matter
of your opinion.

That it is your mistake is a fact. You
must put the script b in a valid place on
the matlab search path. Do not place it
in the matlab toolbox directories. Do not
place it in some random directory that
is not on the path.
