To give you the main idea:

You create a function with all the constants as parameters like

function y = my_integrand(t, k, t_ai, t_hi, omega_ai, omega_hi)
...
endfunction

when you call a integrator like quad with an anonymous function which
has the constants fixed for your special case like

val = quad (@(t) my_integrand(t, ...fixed values ...), -5, 5)

what you put after the t, as the fixed values depends on your program
that needs not to be hardcoded values it can be some variables read from
a file or interactively entered or whatever else.
