Black-Box Toolbox: isa

isa

This function is not yet fully documented. This is a transcript of the text-formatted help.

blackbox/isa  Class detection with sub-type support
   isa(BB,'blackbox') returns true if BB is a black-box operator.

   The black-box variant is extended so you can test if an operator has a
   specific type. Sub-types are separated by a colon:
     isa(BB,'blackbox:matrix')
     isa(BB,'blackbox:counter')

   If you do not provide a type, anything will be matched. For instance
   isa(BB,':counter') is equivalent to the second example.

   If a type has qualifiers, you may also match those. For example
   isa(BB,':matrix:sparse') is true if BB represents a sparse
   Matlab matrix.
