isaUnderlying - True if distributed array's underlying elements are of specified class

Syntax

TF = isaUnderlying(D, 'classname')

Description

TF = isaUnderlying(D, 'classname') returns true if the elements of distributed or codistributed array 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.

Examples

N = 1000;
D_uint8  = distributed.ones(1, N, 'uint8');
D_cell   = distributed.cell(1, N);
isUint8  = isaUnderlying(D_uint8, 'uint8') % returns true
isDouble = isaUnderlying(D_cell, 'double') % returns false
