Index in position 1 exceeds array bounds (must not exceed 46)

Hi,

I am getting this error in my code: Can you please help me with this problem?

Index in position 1 exceeds array bounds (must not exceed 46).

Error in testfile (line 58)

y(n,:)=feval('Fun',T(n),Y(n,:),D(n,:));

Y is 617 by 4 matrix, T is 617 by 1 matrix, D is 46 by 16 matrix

[rY cY]=size(Y);
for n=1:rY
    for m=1:cY       
    y(n,:)=feval('Fun',T(n),Y(n,:),D(n,:));
    end
end
y=y';

The value of n iterates from 1 to 617.

The size of D is 46x16.

When n=47, you get the error because D(47,:) doesn't exist. The last row of D is 46.

y(n,:)=feval('Fun',T(n),Y(n,:),D(n,:));
%                              ^^^^^^

Hence, 'Index in position 1 exceeds array bounds (must not exceed 46).'

Thanks Adam

Can you please let me know how to fix it?

[Adam Danz]

It needs to be fixed at a conceptual level by understanding what the code is supposed to be doing and since this is your code and I have no idea what it's supposed to do, you'll need to think that through.

feval evaluates the function fun using the inputs T, Y, and D. If those variable sizes are correct, you'll need to figure out the correct way to index them.

The actual sizes of T, Y and D are correct. But how can I do the indexing in a right way? Thanks

[Adam Danz]

I don't know. I can't know. Again, the problem needs to be solved at the conceptual level.

I don't know what the function is supposed to be doing.

You need to think about what the function is supposed to be doing and forget about code for a moment.

What should the inputs look like, their shape and size?

How are the T Y and D variables supposed to be combined as inputs?

What does the fun function expect to receive?

These are higher level questions to think about.
