Undefined is a term used when a mathematical result has no meaning. More precisely, undefined values occur when an expression is evaluated for input values outside of its domain. ( 1 if no complex numbers) ( 2 if no complex numbers) ( units in radians, no complex infinity)
MATLAB does not recognize the specified string as the name of a function on the MATLAB path or a variable visible to that function. Undefined function or variable can be caused by: 1) a typographical error when typing a command or variable name (such as typing a 1 [one] when you intended to type an l [low-case L]). 2) changed directories so that a function you used is no longer on MATLAB's search path.
