How do I use the same user input for every iteration?

[putio_d]

I have a function in Matlab that finds the roots of a system of nonlinear equations. It calls for the system function, which is unique to each nonlinear system that I am trying to solve.

What I am trying to do is write a code that uses my root function to solve my system function. However, I also want the user to input the values of the constants in the system equations. If I write that in the system function, with each iteration that the root function does, I have to enter them again. That gets quite tiring.

I guess my question is, is there a trick to set the inputs of the systems function and have them used for every iteration in the root function?

Yes, you can use the input argument of the root function to pass the constants that are used in the system function.For example, suppose your root function is defined as:function x = root(func,x0)Your system function would then be defined as:function f = system(x,c1,c2,c3)and you could call the root function with the constants as:x = root(@System,[x0,c1,c2,c3]);The root function will then pass the constants (c1,c2,c3) to the system function each time it is called.
