Function File: x = mustBeA (x, type) ¶

Function File: x = mustBeA (x, type, label) ¶

Requires that input is of a given type.

Raises an error if the input x is not of type type, as determined by isa (x, type).

label is an optional input that determines how the input will be described in error messages. If not supplied, inputname (1) is used, and if that is empty, it falls back to "input".
