All odeset inputs must be constant, but the anonymous function (which stores the value of params when the anonymous function is constructed) is not.
You can work around this limitation by storing params somewhere other than the anonymous function. For example, a global or persistent variable.
Here's an example of how you could use a global:
function out = xEntryPoint(params)
global g
g = params;
f = @myFun;
coder.const(f); % verifies that f is constant
out = f();
end
function out = myFun
global g
out = g;
end
Generate code and verify it works via:
global g;
g = struct('f', 0);
codegen xEntryPoint -args g
s.f = 4;
xEntryPoint_mex(s)
