expand an empty array into a nonempty array by assigning a specific value into the empty array. Any object you assign to the array must be of the same class or convertible to the class of the empty array. For example, create an empty array ofuint8and try to assign a string value to ...

inputname(argnum) returns the workspace variable name corresponding to the argument number argnum. If the input argument has no name (for example, if it is an expression instead of a variable), the inputname command returns the empty string (”)...
