Find where certain sequence of true/falses is placed inside a logical array

Hello!

Assume that I have the following logical array:

x=[false;false;true;true;true;true;true;false;true;true;true]'

x = 1×11 logical array
   0   0   1   1   1   1   1   0   1   1   1

I would like to construct a logical array which returns true at the index where the sequence [true;false;true] is found

Hence the result would look like this

result=[false;false;false;false;false;false;true;false;false;false;false]'

result = 1×11 logical array
   0   0   0   0   0   0   1   0   0   0   0

Hope that the question is clear, thank you!

x=[false;false;true;true;true;true;true;false;true;true;true]';
f=strfind(x,[1 0 1]);
result=zeros(size(x));
result(f)=1

result = 1×11

0 0 0 0 0 0 1 0 0 0 0

Thank you!

For my purposes I would slightly change the code like this:

x=[false;false;true;true;true;true;true;false;true;true;true]';
f=strfind(x,[1 0 1]);
result=false(size(x));
result(f)=true

result = 1×11 logical array
   0   0   0   0   0   0   1   0   0   0   0
