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

arrayerrorindex

Getting the error code in the title

Code:

New to matlab so thanks for any assistance and patience. I imagine the solution is simple but cannot find it.

Have you created a variable named mass in your workspace? If so, that line of code you wrote will attempt to index into that variable rather than attempting to call your function. If you need the contents of that variable create a new variable with a different name then clear the variable named mass and try calling your function again.

MATLAB: Function ‘subsindex’ is not defined for values of class ‘string’

Rename the variable named title in your workspace so you can use the title function again.

When the error message refers to subsindex, it means you're trying to use an object as the index into a variable but MATLAB doesn't know how to interpret that object as an index and the variable into which you're trying to index hasn't had its indexing implemented to handle that situation.

In your case, you've done something like this but with potentially many lines between the first and second line of my example (so you forgot you created a variable named title) and with title instead of f as the name.

>> f = (1:10).^2;
>> f("5")
Function 'subsindex' is not defined for values of class 'string'.

MATLAB: “Index out of bounds” error

You are trying to access an array element that does not exist. Basically you have something like this:

>> X = [1,2,3]
>> X(4)
Index exceeds matrix dimensions.

Of course this causes an error, because there is no fourth element in X.

However it could be that there is some confusion with the variable taylorexp: although you define it as a variable on this line

taylorexp(order,iterations)=y;

perhaps you thought that that calls your taylorexp function?

I would recommend that you do not give functions and variables the same name (or use the names of any MATLAB functions). If it is supposed to be a function call, what do you imagine that

taylorexp(order,iterations)=y;

should do?
