Matlab编码器Fzero函数

Question

I am trying to convert a MATLAB code to C code using "MATLAB Coder", but anonymous functions are not allowed.

How can I convert for example an fzero function as

myfun = @(x,c) cos(c*x);  % parameterized function
c = 2;                    % parameter
fun = @(x) myfun(x,c);    % function of x alone
x = fzero(fun,0.1)

into a normal function, for instance, to convert the whole code to C.

Answer 1

You have "anonymous" functions, not "undefined" functions, just to clear up the terminology.

To convert the following to a named function:

myfun = @(x,c) cos(c*x);  % parameterized function

write this:

function result = myfun(x,c)

result = cos(c*x);

end

For the second function, write this:

function result = myfun2(x)
c = 2;
result = cos(c*x);

end

Finally, call fzero like this:

x = fzero(@myfun2, 0.1);
