Undefined function - min/max

susan — Tue, 08 Apr 2008 17:09:02 -0400

Hi! I keep getting an error while trying to run code with
this:

mindata=min(data);

The error is "Undefined function or variable "min"."

The same error happens with max. Everything else in the
code works.I can run this from command line though!

how about an example? sometimes you can find the problem
when trying to cut the code down to the shortest section
that reproduces the problem so you can post it, preferably
no more than a half dozen lines or so.

maybe put a 'which min' and 'whos min' just before the
error line. or use the debugger to stop on error and then
do the which and whos command to see what it thinks 'min'
really means at that point.

when you were experimenting with code, you created a
variable named "min" and "max".

Now min and max don't live here anymore.

Restart Matlab and search your scripts for where you
assigned a value to min and max. Then change their names to
a non protected name. Even MIN and MAX will work.

I have the same problem with 'size' because stuff I analyze
has size as an object description.... !

no, in this case the OP would have received a different
error -or- depending oh the type of <min>/<max>, no error
at all...
