True if distributed array's underlying elements are of specified class
TF = isaUnderlying(D, 'classname')
TF = isaUnderlying(D, ' returns
true if the elements of distributed or codistributed array classname')D are
either an instance of classname or an instance
of a class derived from classname. isaUnderlying supports
the same values for classname as the MATLAB® isa function does.
N = 1000; D_uint8 = ones(1,N,'uint8','distributed'); D_cell = distributed.cell(1,N); isUint8 = isaUnderlying(D_uint8,'uint8') % returns true isDouble = isaUnderlying(D_cell,'double') % returns false
