Substitute variables in function handle
显示 更早的评论
Hello,
I have two implementations.
- Create functions based on the parameter
- Pass this functions to another function and evaluate them there
I'm creating functions like this:
for i=1:n/2-1
funk{i} = @(x)2*x(i)-2+400*x(i)^3-400*x(i)*x(i+1);
end
I want this to create multiple functions (depends on n) with i to be superset by a number, but WITHOUT being solved right away as i want to hand it over to another function in which this should get solved.
How can I achieve this?
Thanks in advance

You can try:
funk = @(xi1,xi2)2*xi1-2+400*xi1^3-400*xi1*xi2;

What you have already done should work.
Although all of the function handles will look the same, they would have captured different values of i
For example,
for i = 1 : 2
funk{i} = @(x)2*x(i)-2+400*x(i)^3-400*x(i)*x(i+1);
end
ws1 = functions(funk{1}).workspace{1}
ws2 = functions(funk{2}).workspace{1}
Notice how the information embedded within the function handles funk{1} and funk{2} is different -- they have different embedded i values.

x = [1 2 3 4 5 6];
for i = 1 : 2
funk{i} = @(x)2*x(i)-2+400*x(i)^3-400*x(i)*x(i+1);
end
test(funk,x)
function test(fun,x)
fun{1}(x)
fun{2}(x)
end
