error message

[Andreu Corominas Murtra]

Hi!

I've an error when executing the command "find", but I don't understand 
the error message. Does anybody understand it?

***************************************************
-->find( kXY(:) > 100 )
                           !--error 144
Undefined operation for the given operands.

check or define function %s_2_s for overloading.
***************************************************

where kXY is a matrix of size 1 x 3240. I've plotted it and it stores 
valid data (no "nan" or other strings ....)

I'm quite lost because I use the same command with other vectors without 
problem ...


Thanks!

andreu
