detect consecutive duplicates in a structure

Hi all

I am trying to detect consecutive duplicates in a structure like this

A(1).a=1
A(2).a=1
A(3).a=3
A(1).b=true
A(2).b=true
A(3).b=false

A has many .a .b ...

I did a for loop with this test :

ttest=A(ii)==A(ii-1)

But I get the error

Undefined function 'eq' for input arguments of type 'struct'.

So I described every .a .b ... individually

all([A(ii).a == A(ii-1).a,A(ii).b == A(ii-1).b,...])

which is a pain and lakes evolutivity

How would you do that ?

Regards

Julien

A(1).a=1
A(2).a=1
A(3).a=3
A(1).b=true
A(2).b=true
A(3).b=false

for ii=2:3
    ttest(ii-1)=A(ii).a==A(ii-1).a
end
for ii=2:3
    ttest(ii-1)=A(ii).b==A(ii-1).b
end

H = squeeze(struct2cell(A));
[~,~,c] = unique(reshape([H{:}],size(H)));
ttest = histc(c,unique(c));
