I am exciting ultrasound in wateter which then gooes through the material. I want to notrmalise my signal in such a way that it is scaled by having my input signal and the front wall of my material the same amplitude say, an amplitude of 1. Below is an image of what I have just now. I am not what steps I would need to take to scale this signal. I have been told it is a standard thing that can be achieved in Matlab
.

I will post extra information and what I have. Both my Time and Data are of the size (8600 x 1 ). Any ideas how I can go abot normalising/scaling this would be greatly appreciated. Dave :)
%Load in files
FName = 'Tit_10MHz_110F.flxhst';
MyData = read_history(FName);
% Load in Data and Time signals from each file
Time = MyData.TimeRecB.Time;
Data= MyData.DataRecB(1).Data;
figure(01)
plot(Time,Data)
xlabel('Time(s)')
xlim([0 7e-6])
ylabel('Amplitude')
