Is it possible to reference an array of inline functions or function handles created within a structure in MATLAB?

Is it possible to reference an array of inline functions or function handles created within a structure in MATLAB?

The following example demonstrates this problem:

f1 = inline('sin(x)');

f2 = inline('cos(x)');

h.f(1) = f1;

I now calculate

h.f(pi/2)

 ans =

       1

But if I define:

h.f(2) = f2

I get

 h =

      f: [1x2 inline]

Now I try to calculate inline results:

h.f([pi/2;pi/2])

I receive the error

 ??? Comma separated list must have exactly one item.

How can I reference the index of the vector of the inline functions, as well as pass an argument?

You should not create the vector of inline functions. When you do this without a structure, you receive an error.

f1 = inline('sin(x)');

f2 = inline('cos(x)');

f(1) = f1;

f(2) = f2

 ??? Comma separated list must have exactly one item.

To work around this error, rather than creating a vector of inline functions, you should create a cell array. Here is an example:

     f1 = inline('sin(x)');

     f2 = inline('cos(x)');

     h.f{1} = f1;

     h.f{2} = f2;

     h.f{2}(pi/4),

This produces the correct result:

    ans =

    0.7071

You can also do this with function handles

f{1}=@sin;

f{2}=@cos;

feval(f{1},1);
