The argument obj is a matlab objector an object of the Java programming language. The argument class_name isthe name of a MATLAB (predefined or user-defined) or a Java class.Predefined MATLAB classes include logical Logical array of true and false values char Characters array numeric Integer or floating-point array integer Signed or unsigned integer array int8 8-bit signed integer array uint8 8-bit unsigned integer array int16 16-bit signed integer array uint16 16-bit unsigned integer array int32 32-bit signed integer array uint32 32-bit unsigned integer array int64 64-bit signed integer array uint64 64-bit unsigned integer array float Single- or double-precision floating-point array single Single-precision floating-point array double Double-precision floating-point array cell Cell array struct Structure array function_handle Function handle 'class_name' MATLAB class or Java class To check for a sparse array, use issparse.To check for a complex array, use ~isreal. Examples isa(rand(3,4),'double') ans = 1 The following example creates an instance of the user-defined MATLAB classnamed polynom. The isa functionidentifies the object as being of the polynom class. polynom_obj = polynom([1 0 -2 -5]); isa(polynom_obj, 'polynom') ans = 1 复制代码有没有高手给翻译下？ 0
