Hi people,
I have an array of functions, something like func(x,y)=[func1(x,y) func2(x,y) ... funcN(x,y)]
Now I want to integrate func(x,y). I.e., I want to integrate each component of func(x,y). How can I do that?
All information I could find are about function of arrays, instead of array of functions.
Thanks in advance.

In this calculation i have assumed that you are doing double integration first w.r.t y then x. First define symbolic matrix. Then perform double integration.
>> syms x y
>> a=[x.^2+y x+y];
>> int(int(a,y, 0, sin(x)), 0, pi)
In this calculation y limit is from 0 to sin(x) and x limit is from 0 to pi.

Thanks a lot! This works!
I also found another solution.
>> funchandler={@(x,y)x^2+y, @(x,y)2x,@(x,y)x-y};
Then I can proceed to integrate using
>>dblquad(funchandler{1},xmin,xmax,ymin,ymax)
etc.

There is no routine provided for this, unless perhaps the Symbolic Toolkit could handle it.
