MATLAB: Non-looping way to compare cellstr arrays of different sizes

cellstr array comparein-lineismemberMATLABunequal size

Suppose A = {'aa', 'kk', 'ccc'}, B = {'aa', 'bb', 'cc', 'dd', 'ee'}.

Is there a not-explicitly-looping way to return a logical array the same size as A that is 1 where an element of A is in B, 0 where it is not, e.g.,

"whereMember"(A,B) => [1 0 0]?

Thanks!

A = {'aa', 'kk', 'ccc'};
B = {'aa', 'bb', 'cc', 'dd', 'ee'};
ismember(A,B)

Can just use an anonymous function:

clc
close all
clear all
getVarsetTable = @(t,userPrefix) t(:,contains(t.Properties.VariableNames,userPrefix));
year1 = {1994, 1994, 1994, 1994, 1994, 1994, 1994, 1994, 1994}.';
year2 = {1995, 1995, 1995, 1995, 1995, 1995, 1995, 1995, 1995}.';
type1 = {'AA', 'AA', 'AA', 'AA', 'AA', 'AA', 'AA', 'AA', 'AA'}.';
type2 = {'BB', 'BB', 'BB', 'BB', 'BB', 'BB', 'AA', 'BB', 'BB'}.';
gof1 = {'CC', 'CC', 'CC', 'CC', 'CC', 'CC', 'CC', 'CC', 'CC'}.';
gof2 = {'DD', 'DD', 'DD', 'DD', 'DD', 'DD', 'DD', 'DD', 'DD'}.';
t = table(year1, type1, year2, type2, gof1, gof2);
t1 = getVarsetTable(t,{'year','type'});
t2 = getVarsetTable(t,{'year','gof'});

Or if you really want a separate function

function [t] = getVarsetTable(t,userPrefix)
idx = contains(t.Properties.VariableNames,userPrefix);
t = t(:,contains(t.Properties.VariableNames,userPrefix));
end
