MATLAB: Genvarname -> Index exceeds matrix dimensions.

genvarname

Hi everyone~

I have a quite stupid question here.

genvarname doesn't work here, like this:

>> vname = genvarname ('aaa') Index exceeds matrix dimensions.

Can anyone let me know what the problem is? Thank you~

You have defined a variable named genvarname

MATLAB: I keep getting index exceeds matrix dimensions but I don’t understand why. I’m trying to sum the elements in an array.

Somewhere earlier in your code you have a variable named ‘sum’ that is ‘overshadowing’ the sum function. Rename the variable to something other than ‘sum’ (or the name of any other MATLAB function) and the problem will disappear.

How about just using dynamic fieldnames?

a.someString = pi
fn = fieldnames(a);
a.(fn{1})

What are you trying to do?

For your example:

b.a5 = pi
b.(['a' num2str(5)])
