This MATLAB function evaluates a function using its name or its handle, and using the input arguments x1,...,xM.
feval只接受函数名，试试这样：函数：(simpr1.m)function s=simpr1(f,a,b,n)h=(b-a)/(2*n);s1=0;s2=0;for k=1:n x=a+h*(2*k-1);s1=s1+feval(f,x);end for k=1:(n-1)x=a+h*2*k;s2=s2+feval(f,x);end s=h*(feval(f,a)+feval(f,b)+4*s1+2*s2)/3;-...
The feval function enables an object to behave like a function in MATLAB®. You can pass feval to another function that accepts a function input, such as fminsearch and integral. feval can be simpler to use with a model created from a table or dataset array. When you have new predictor...
Pramit Biswas' example is of a function that accepts an array input as 테마복사 function f = funfunc(array) a=array(1); b=array(2); f = a+b ; end In your code, you are not passing a handle to a function but are instead passing the scalar value f. 댓글 수: 0 ...
Note It is not necessary to use feval to call a function by means of a function handle. This is explained in Calling a Function Using Its Handle in the MATLAB? Programming Fundamentals documentation.[y1, y2, ...] = feval(function, x1, ..., xn). If function is a ...
MATLAB中feval函数的用法是什么? feval函数的功能是求函数值。基本使用格式:y=feval(fhandle, x) %fhandle——函数表达式,x——变量值[y1, y2, ...] = feval(fhandle, x1,..., xn)具体实例:myfun=inline('x^3+3*cos(x)+sin(y)','x','y');x=pi;y=pi;a=feval(myfun,x,y
[y1,..,yn] = FEVAL(F,x1,...,xn) returns multiple output arguments.Within methods that overload built-in functions, use BUILTIN(F,...)to execute the original built-in function. Note that when using BUILTIN, F must be a function name and not a function handle.函数的求值...
This MATLAB function evaluates the cfit object cfun at the predictor values in the column vector x and returns the response values in the column vector y.
