iptcheckhandle() - Image Processing

iptcheckhandle(H, valid_types, func_name,
var_name, arg_pos) checks the validity of the handle H and
issues a formatted error message if the handle is invalid. H must
be a handle to a single figure, uipanel, hggroup, axes, or image object.valid_types is a cell array of strings specifying
the set of Handle Graphics object types to which H is
expected to belong. For example, if you specify valid_types as {'uipanel','figure'}, H can
be a handle to either a uipanel object or a figure object.func_name is a string that specifies the
name used in the formatted error message to identify the function
checking the handle.var_name is a string that specifies the name
used in the formatted error message to identify the argument being
checked.arg_pos is a positive integer that indicates
the position of the argument being checked in the function argument
list. iptcheckhandle converts this value to an
ordinal number and includes this information in the formatted error
message.
