in [Matlab]

From: Narendra on 17 May 2010 08:07 Is there any integration function (Like quad) accept input f(x,y) and give output as a function of x after doing integration with respect to y for given limits... so that after manipulating, modifying and involving some other function of x, Integrate again with respect to x.

Limits of X=0 to 1 and Y=0 to 1 I Find Integration [{Integration ( f (x,y) ) dy }^2 ] x dx ... I use syms , splitting the fun on y=x and i find >> syms s y int( ( (int(x*y+y^2,y,0,x) + int(x*y,y,x,1) )^2) *x , x , 0 , 1) ans = 19/144... result i checked manually supported by FORTRAN too. Here the issue is .. -I want to incorporate fun with if statement. -f(x,y) is bunch of available statistical functions.. for variable input. I am searching a function for integration take input f(x,y) and limits of y.. integrate with respect to y and give out put as g(x). without using syms.. actually when i use syms.. I am not able to involve statistical function in f(x,y) as they give numerical values.
