Is there any function in Matlab like conv(u,v) but that sums up 'u(x)' and 'v(x)' instead of multiplying them?
u(x) = 66*(x-6)
v(x) = 6*(x-9)
Applying this "wanted function"...
sum = wantedfunction(u,v)
sum(x) = 66*(x-6) + 6*(x-9)
I believe you can do what you are asking for using anonymous functions:
u = @( x ) ( 66 * (x - 6) ); v = @( x ) ( 6 * (x - 9) ); w = @( x ) ( u(x) + v(x) );
w the "sum" function you wanted - if I understood your question correctly.
Example: after I keyed in the above, I found
-378 -306 -234 -162 -90
It's possible I completely missed the point of your question - if so, please leave a comment.
If by "conv" function you mean convolution then the equivalent of that for your case is simply adding two functions you want and then multiply them by delta(your desired spacing on x axis) and then sum over that, gives your function. Still you need to iterate this process by a "for" loop for different delays.
