问题
I have an anonymous function A taking two arguments. I need to convert this function so it takes one argument, by changing the other argument to a constant.
For example having a function:
A = @(X, Y) X + Y;
I would like now to have:
B = @(Y) 3 + Y;
This seems to be a normal thing to do in mathematics, so I guess there is a way to do such thing in MATLAB. I cannot find the solution though.
The reason I need to do something like this is that I have a function that does some calculations on A, but also needs to solve problems when one of the A's arguments is constant. For example find a minimum of the A for X = 3.

You can use the same anonymous function and put X as 3 in it but if you want to create another anonymous function, here is how to do that:
A = @(X, Y) X + Y;
B = @(Y) A(3,Y); %Here you have put X=3
To verify:
>> A(3,4)
ans =
7
>> B(4)
ans =
7
