From: m y on 31 Dec 2009 15:57 Hey all Does anybody know about the multivariable function in matlab. I have a function f=(f1,f2)' with two components f1 and f2. where f1= function of x,y , f2 also depends on x,y coordinates ..Kindly guide me if there is vecor valued function in matlab? Best regards

Any function that returns a vector is a vector valued function. John

I know that it is a vector valued but I am looking for a command for vector valued function. One way is simply define each component as a scalar function, but thats not the case with my problem. I want to look at function where you give input vectors and function command on the given input will result a vector. > John

You need to start reading the getting started documentation. John

I don't know if it helps, but here's an example >> f=@(x,y) [x+y;x-y] %A vector-valued function f = @(x,y)[x+y;x-y] >> f(1,2) %evaluate at x=1, y=2 ans = 3 -1 |
