Two Array merging into one based on range

Hello team,

I have to 2 time series array:

Signal_1= [20, 10];

Signal_2 = [ 40, 20, 40, 10, 40];

I want to merge or insert Signal_1 into Signal_2 based range and Signal_1 completely enclosed between Signal_2.

Range_1 = peak2peak(Signal_1); % 10

Range_2 = peak2peak(Signal_2); % [20 20 30 30]; Although this will 30 alone but in array i mentioned range for each 2 values

Based on range, Range_1<Range_2, it can be merged into any of these values.

But [20 10] lies outside [40 20 40] range. While it enclosed between [40 10 40].

Please help in writing code for this this.

Final expected result = [40 20 40 10 20 10 40]
