Domain Of A Function Matlab

Function y1 yn myfun x1 xm declares a function named myfun that accepts inputs x1 xm and returns outputs y1 yn this declaration statement must be the first executable line of the function.

Domain of a function matlab. The function f defined by f x x whose domain x x r and range f x f x 0 i would like to know how matlab can return the domain and range of a function i e. It consists of a single matlab expression and any number of input and output arguments. Anonymous functions are not stored to any program file. Specify a function of the form y f x.

An anonymous function is like an inline function in traditional programming languages defined within a single matlab statement. For example use times instead of. You can define an anonymous function right at the matlab command line or within a function or script. You must know what function you want to graph because you need to let matlab know what independent variables your function has before you write the function.

Use array operators instead of matrix operators for the best performance. Learn more about matlab domain function matlab. Then i can find the minimum maximum and gradient. They can accept multiple inputs and return outputs.

I don t know of any way to tell the built in matlab function gradient what the domain is but it seems to be doing ok. The function must accept a vector input argument and return a vector output argument of the same size. Specify domain of a function. In addition i have vectors for x and y that map the indices of the matrix to the values between 1 and 1.

Valid function names begin with an alphabetic character and can contain letters numbers or underscores. Know what function you want to graph. Some examples of anonymous functions include. I don t know of any way to tell the built in matlab function gradient what the domain is but it seems to be doing ok.
