We have followed the example as it is described in the manual but we keep getting the following error -
Error using /
Matrix dimension must agree
tone_burst_offset = 40 = element_spacing*element_index*sin(steering_angle*pi/180)/(medium.sound_speed*dt);
This is how we have defined the following matrices
steering_angle = 30;
medium.sound_speed = 1500*ones(Nx,Ny);
medium.sound_speed(1:Nx/2,:) =1800;
dt = (.5*10^-6)^-1;
Hi Suryakant,
You've defined medium.sound_speed as a matrix, but perhaps when defining tone_burst_offset you want to divide by a single value of sound speed ie. the value of the sound speed where the source is located?

Thank you for helping me. So, I tried to do what you said but I am now getting this error :-
>> LinearArray
User defined classes not supported, returning grid structure...
Hi Suryakant,
Perhaps it's easiest to start with one of the examples that are included in the toolbox (e.g., Simulating Ultrasound Beam Patterns). First make sure you can run this, and then make the modifications you need? You can access the examples through the MATLAB help browser (click on "Supplemental Software" if you are using a recent version of MATLAB).
Brad.
